RP101x SERIES
300mA LDO Voltage Regulator
NO. EA-167-070305
OUTLINE
The RP101 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 RP101 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 SOT23-5
and PLP1612-4 (height=0.6mm type) or PLP1612-4B (height=0.4mm type), therefore high density mounting of
the ICs on boards is possible.
