OUTLINE

The RP101x 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 RP101x 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 SOT-23-5 and

DFN(PLP)1612-4 (t

0.6mm type) or DFN(PLP)1612-4B (t0.4mm type), therefore high density mounting of the

ICs on boards is possible.
