General Description
Features
Data Sheet
AP2402
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.
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
devices. The chip-enable function allows the output of
each channel to be turned on/off independently, greatly
reducing the power consumption.
· 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)
· Operating Temperature: -40 to 85oC
· Compatible with Low ESR Ceramic Capacitor
Applications
The AP2402 series have 2.5V/1.8V, 2.8V/1.8V and
2.8V/2.8V versions.
·
Mobile Phones, Cordless Phones
· Wireless Communication Equipment
