AP2402
General Description
Features
The AP2402 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 protection
and a chip enable circuit with quick discharge function.
·
Minimum Output Current Capability per Channel:
300mA
High Output Voltage Accuracy: ±2%
Low Quiescent Current per Channel: 50µA Typi-
cal
Low Standby Current: 0.1µA Typical
High PSRR: 70dB Typical （f=1kHz)
Extremely Low Noise: 30µVrms (10Hz to
100kHz)
·
·
·
·
·
The AP2402 series feature high supply voltage ripple
rejection, low dropout voltage, low noise, high output
voltage accuracy, and low current consumption which
make them ideal for use in various battery-powered
o
·
Operating Temperature: -20 to 60 C
devices. The chip-enable function allows the output of · Compatible with 2.2µF Low ESR Ceramic Capac-
each channel to be turned on/off independently, greatly
itor
reducing the power consumption.
Applications
The AP2402 series have 2.5V/1.8V, 2.8V/1.8V, 2.8V/
2.8V, 2.8V/3.3V and 3.3V/3.3V versions.
