300mA HIGH SPEED, EXTREMELY LOW NOISE CMOS LDO REGULATOR

General Description

Features

AP2128

The AP2128 Series are positive voltage regulator ICs · Wide Operating Voltage: 2.5V to 6V

fabricated by CMOS process. The AP2128 provides · Low Dropout Voltage (3.3V only):

two kinds of output voltage operation modes for

170mV@300mA

setting the output voltage. Fixed output voltage mode · High Output Voltage Accuracy: ±2%

senses the output voltage on VOUT, adjustable output

voltage mode needs two resistors as a voltage divider

· High Ripple Rejection:

65dB@ f=1kHz, 45dB@ f=10kHz

· Low Standby Current: 0.1µA

The AP2128 Series have features of low dropout

voltage, low noise, high output voltage accuracy, and

low current consumption which make them ideal for

use in various battery-powered devices.

· Low Quiescent Current: 60µA Typical

· Low Output Noise: 60µVrms

· Short Current Limit: 50mA

· Over Temperature Protection

· Compatible with Low ESR Ceramic Capacitor:

AP2128 has 1.0V, 1.2V, 3.3V fixed voltage version and

1µF for CIN and COUT

0.8V to 4.5V adjustable voltage version.

· Excellent Line/Load Regulation

· Soft Start Time: 50µs

AP2128 series are available in SOT-23-5 Package.

· Auto Discharge Resistance: RDS(ON)=60Ω

Applications

· Datacom

· Notebook Computers

· Mother Board
