DUAL LDO REGULATORS
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 （f=1kHz)
· Extremely Low Noise: 30µVrms (10Hz to
100kHz)
· Operating Temperature: -40 to 85oC
· 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
3.3V and 2.8V/1.8V versions.
· Wireless Communication Equipment
· Portable Games
The AP2401 are available in standard SOT-23-6 pack- · Cameras, Video Recorders
age. · Sub-board Power Supplies for Telecom Equip-
ment
· Battery Powered Equipment

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated
under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods
may affect device reliability.
