RP115x-Y Series

Low On Resistance/ Low Voltage 1 Ch 500 mA/ 1.0 A Alternative LDO

for Industrial Applications

No.EA-413-190819

OUTLINE

The RP115x is a positive voltage regulators featuring 500 mA/ 1.0 A that provide high ripple rejection, low

dropout voltage, high output voltage accuracy, and low supply current. Internally, the RP115x consists 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 uses CMOS process for

achieving low supply current, low On Resistance for low dropout voltage (Typ. 0.195 V (DFN1216-8, I

OUT

= 1.0

A, V

SET

= 1.2 V)) and CE function for long battery life.

The RP115x is available in the DFN1216-8 package for space saving and the SOT-89-5 (Output current: 1.0

A fixed) package for higher power applications. The RP115L (DFN1216-8 package) can choose the output

current limit between 1.0 A or 500 mA by alternating the LCON pin between “High” or “Low”. The RP115H

(SOT-89-5 package) can output only 1.0 A since it does not include the LCON pin. This is a high-reliability

semiconductor device for industrial application (-Y) that has passed both the screening at high temperature

and the reliability test with extended hours.
