RP101x SERIES
LOW NOISE 300mA LDO REGULATOR
NO.EA-167-070903
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
PLP1612-4 (t=0.6mm type) or PLP1612-4B (t=0.4mm type), therefore high density mounting of the ICs on
boards is possible.
