RP130x Series

AEC-Q100 Grade 2 Compliant

Low Noise 150mA LDO Regulator for Automotive Applications

NO.EC-173-150413

OUTLINE

The RP130x is a CMOS-based positive voltage regulator IC with high ripple rejection, low dropout voltage, high

output voltage accuracy and extremely low supply current. The RP130x consists of a voltage reference unit, an

error amplifier, a resistor network for voltage setting, a short current limit circuit, and a chip enable circuit.

The RP130x has low supply current characteristics in the CMOS process. In addition, the RP130x can supply

a low dropout voltage, which becomes the smallest difference between the input voltage and output voltage by

having a low on-resistance and also can achieve the battery's long life by a chip enable function.

When compared with the conventional products of high-speed type, the RP130x achieves low consumption

current of 38A (Typ.) while improving the input transient response, the load transient response, and the ripple

rejection.

The RP130x supports two package types: SOT-23-5 and DFN1212-4. By the adoption of the ultra-compact

DFN1212-4, the RP130x can achieve a higher density mounting than ever.
