RP115x SERIES
Low On Resistance/ Low Voltage 1ch 500mA/ 1.0A Alternative LDO
NO. EA-274-150708
OUTLINE
The RP115x Series are CMOS-based positive voltage regulators featuring 500mA/ 1.0A that provide high
ripple rejection, low dropout voltage, high output voltage accuracy, and low supply current. Internally, the RP115x
Series consist of a voltage reference unit, an error amplifier, a resistor-net for output voltage setting, a current
limit circuit, a thermal shutdown circuit, and a reverse current protection circuit.
The RP115x Series uses CMOS process for achieving low supply current, low On Resistance for low dropout
voltage (TYP. 0.195V (DFN1216-8, IOUT=1.0A, VSET=1.2V)) and CE function for long battery life.
Excellent ripple rejection, input transient response, and load transient response make this series ideal for the
power sources of mobile communication equipments.
The RP115x Series are available in the DFN1216-8 package for space saving and the SOT-89-5 (Output
current: 1.0A fixed) package for higher power applications.
The RP115L Series (DFN1216-8 package) can choose the output current limit between 1.0A or 500mA by
alternating the LCON pin between “H” or “L”.
The RP115H Series (SOT-89-5 package) can output only 1.0A since it does not include the LCON pin.

TECHNICAL NOTES
Phase Compensation
In LDO (Low Drop Out) regulators, phase compensation is provided to secure stable operation even when
the load current is varied. For this purpose, use a capacitor COUT with 1.0μF or more and proper ESR
(Equivalent Series Resistance).
Depending on the capacitor size, manufacturer, and part number, the bias characteristics and temperature
characteristics are different. Evaluate the circuit taking actual characteristics into account. Especially for the
1.75-V-output product, it is recommended to use 2.2µF or higher output capacitor when the product is used
under the low-temperature environment such as −20°C or lower.
If you use a tantalum type capacitor and the ESR value of the capacitor is large, the output might be
unstable. Evaluate your circuit including consideration of frequency characteristics.
PCB Layout
Ensure the VDD and GND lines are sufficiently robust. If their impedance is too high, noise pickup or unstable
operation may result. Connect a capacitor CIN with 1.0μF or more between VDD and GND pins, and as close as
possible to the pins.
Likewise, connect COUT capacitor with suitable values between the VOUT and GND pins, and as close as
possible to the pins.

REVERSE CURRENT PROTECTION CIRCUIT
The RP115x Series include a Reverse Current Protection Circuit, which stops the reverse current from VOUT
pin to VDD pin or to GND pin when VOUT becomes higher than VIN.
Usually, the LDO using Pch output transistor contains a parasitic diode between VDD pin and VOUT pin.
Therefore, if VOUT is higher than VIN, the parasitic diode becomes forward direction. As a result, the current
flows from VOUT pin to VDD pin.
The ICs of this series switches the mode to the reverse current protection mode before VIN becomes lower
than VOUT by connecting the parasitic diode of Pch output transistor to the backward direction, and connecting
the gate to VOUT pin. As a result, the Pch output transistor is turned off. However, from VOUT pin to GND pin,
via the internal divider resistors, very small current IREV flows.
Switching to either the normal mode or to the reverse current protection mode is determined by the
magnitude of VIN voltage and VOUT voltage. For the stable operation, offset and hysteresis are set as the
threshold. The detector threshold is set to VREV_DET and the released voltage is set to VREV_REL. Therefore, the
minimum dropout voltage under the small load current condition is restricted by the value of VREV_REL.
Following figures show the diagrams of each mode, and the load characteristics of each mode. When giving
the VOUT pin a constant-voltage and decreasing the VIN voltage, the dropout voltage will become lower than
VREV_DET. As a result, the reverse current protection starts to function to stop the load current.
By increasing the dropout voltage higher than VREV_REL, the protection mode will be released to let the load
current to flow. If the dropout voltage to be used is lower than VREV_REL, the detection and the release may be
repeated.
The operating voltage guaranteed level of the reverse current protection circuit is for VOUT ≥ 0.7V. If VIN=0V,
the reverse current protection mode becomes always active.

START-UP CHARACTERISTICS
Constant slope circuit is included in the RP115x Series to prevent the overshoot of the output voltage.
The start-up time (tON) is 100µs (Typ.).
If inrush current increases due to the large capacitance of COUT, the operation mode will be shifted from
Constant Slope (CS) mode to Constant Current (CC) mode. The CC mode maintains a constant level of
inrush current. In the CC mode, tON varies according to the size of COUT and the amount of load current.
Start-up Time and Inrush Current Estimations
Start-up time and inrush current in the CS mode and the CC mode can be estimated as follows.
・CS Mode
Start-up Time: tON = 100μs (TYP.)
Inrush Current: IRUSH = COUT ∙ VSET / tON + IOUT*19
Note: If the result of the above calculation is more than the following values, the operation mode will be
shifted from the CS mode to the CC mode.
LCON=”L”······························· 300mA (TYP.)
LCON=”H” ······························ 500mA (TYP.)

IOUT: When RLOAD is connected to load, IOUT can be calculated by RLOAD = VSET / IOUT.
ICO: ICO is a charge current of COUT and can be calculated roughly by IRUSH ≈ ICO + IOUT.

Precautions Before Use
During the start-up, the inrush current limit circuit is in operation; therefore, the load current (IOUT) should be
drawn after the output voltage (VOUT) reached the preset value (Best timing: tON + 60µs or more). If the load
current is drawn during the start-up, it should be within the following values.
LCON=”L” ···················································· IOUT ≤ 150mA
LCON=”H”···················································· IOUT ≤ 350mA
In the CC mode, IRUSH is limited until VOUT reaches the preset value. IRUSH ≈ ICO + IOUT is true; therefore, if large
IOUT is drawn during the start-up, the charge current (ICO) of COUT decreases and tON becomes longer. Please
refer to Start-up Time and Inrush Current Estimations.
In order to control the start-up operation by using the CS mode or CC mode, input “H” into the CE pin while
VIN ≥ 1.4V. If “H” is input into the CE pin while VIN is less than the minimum operating voltage, the operation may
not be controlled by the CS mode or CC mode.
When starting up the device while the short circuit is occurring between the VOUT pin and GND, the short
current protection circuit does not control the current but the current limit circuit does.
When there’s excessive heat generation in the device, thermal shutdown circuit shuts down the circuitry before
the device overheats dangerously.

LCON PIN OPERATION
By alternating the LCON pin between “H” or “L”, the RP115L can choose the output current limit either
1.0A or 500mA. Please note that during start-up (tON + 60µs (TYP.)), do not change the logic of the LCON
pin.

Short Current Limit vs. Temperature and Current Limit vs. Temperature
The RP115x contains a peak current limit circuit which protect the regulator from damage by overcurrent
if the output pin (VOUT) and the ground pin (GND) are shorted. The short-circuiting causes the overheating
of the device which leads a thermal shutdown circuit to operate. If the peak current limit circuit and the
thermal shutdown circuit work at the same time, fold-back type dropping characteristics cannot be
measured. As for the short-circuit current and the peak current limit circuit, please refer to 3) Short Current
Limit vs. Temperature and 4) Current Limit vs. Temperature.
