General Description
Features
Data Sheet
AP2401
The AP2401 series are dual positive voltage regulator
ICs fabricated by CMOS process. Each of these ICs
consists of a voltage reference, two error amplifiers,
two resistor networks for setting output voltages. Each
channel has a current limit circuit for current protec-
tion.
The AP2401 series feature high ripple rejection, low
dropout voltage, low noise, high output voltage accu-
racy, and low current consumption which make them
ideal for use in various battery-powered devices. The
chip enable function allows the output of each channel
to be turned on/off independently, greatly reducing the
power consumption.
· Maximum Output Current/Channel: More Than
150mA (300mA Limit)
· High Output Voltage Accuracy: ±2%
· Low Quiescent Current/Channel: 25µA Typical
· Low Standby Current: 0.1µA Typical
· High PSRR: 70dB Typical čf=1kHz)
· Extremely Low Noise: 30µVrms (10Hz to
100kHz)
· Operating Temperature: -40 to 85^oC
· Compatible with Low ESR Ceramic Capacitor
Applications
The AP2401 series have 1.8V/2.5V, 1.8V/2.8V, 1.8V/ ^{· Mobile Phones, Cordless Phones}
