RP151K SERIES

300mA 2ch LDO with VD

OUTLINE

NO. EA-132-070724

The RP151 Series are CMOS-based dual voltage regulator (LDO) ICs equipped with a voltage detector (VD).

LDO function has features of high output voltage accuracy, low supply current, low dropout, and high ripple

rejection. Each of these voltage regulator ICs consists of a voltage reference unit, an error amplifier, resistors for

setting Output Voltage, a current limit circuit, and a chip enable circuit.

These ICs perform with low dropout voltage due to built-in transistor with low ON resistance, and a chip enable

function prolongs the battery life of each system. The line transient response and load transient response of the

RP151 Series are excellent, thus these ICs are very suitable for the power supply for hand-held communication

equipment.

The output of built-in voltage detector is Nch open drain type.

The output voltage of these ICs is internally fixed with high accuracy (1%). Since the packages for these ICs

are PLP2020-8 package, 2ch LDO regulators and VD are included in each packages, high density mounting of

the ICs on boards is possible.
