RP100x SERIES

LOW NOISE 200mA LDO REGULATOR

NO.EA-140-070831

OUTLINE

The RP100x 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 RP100x 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, therefore high density mounting of the ICs on boards is possible.
