1 / 22 page Data Sheet 1 Oct. 2009 Rev. 1. 4 BCD Semiconductor Manufacturing Limited DUAL LDO REGULATORS AP2401 General Description 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. The AP2401 series have 1.8V/2.5V, 1.8V/2.8V, 1.8V/ 3.3V and 2.8V/1.8V versions. The AP2401 are available in standard SOT-23-6 pack- age. Features · Maximum Output Current/Channel: More Than 150mA (300mA Limit) · High Output Voltage Accuracy: ±2% · Low Quiescent Current/Channel: 25 µA Typical · Low Standby Current: 0.1 µA Typical · High PSRR: 70dB Typical (f=1kHz) · Extremely Low Noise: 30 µVrms (10Hz to 100kHz) · Operating Temperature: -40 to 85oC · Compatible with Low ESR Ceramic Capacitor Applications · Mobile Phones, Cordless Phones · Wireless Communication Equipment · Portable Games · Cameras, Video Recorders · Sub-board Power Supplies for Telecom Equip- ment · Battery Powered Equipment Figure 1.
