∗RP103Qxx2 (SC-88A) is the discontinued product. As of April in 2016

OUTLINE

The RP103x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely low

supply current, low ON-resistance, and high ripple rejection. Each of these ICs consists of a voltage reference

unit, an error amplifier, resistor-net for voltage setting, a current limit circuit, and a chip enable circuit.

These ICs perform with low dropout voltage and a chip enable function. The line transient response and load

transient response of the RP103x Series are excellent, thus these ICs are very suitable for the power supply for

hand-held communication equipment.

The output voltage of these ICs is fixed with high accuracy. Since the packages for these ICs are

DFN(PLP)1010-4, SC-82AB, SC-88A, SOT-23-5, therefore high density mounting of the ICs on boards is

possible.
