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:170mV@300mA for
two kinds of output voltage operation modes for
setting the output voltage. Fixed output voltage mode
senses the output voltage on VOUT, adjustable output
voltage mode needs two resistors as a voltage divider.
·
·
VOUT=3.3V, 140mV@300mA for VOUT=5.2V
High Output Voltage Accuracy: ±2%
High Ripple Rejection:
68dB@ f=1kHz, 54dB@ f=10kHz
The AP2128 series have features of low dropout · Low Standby Current: 0.1µA
voltage, low noise, high output voltage accuracy, and · Low Quiescent Current: 60µA Typical
low current consumption which make them ideal for · Low Output Noise: 60µVrms@VOUT=0.8V
use in various battery-powered devices.
· Short Current Limit: 50mA
· Over Temperature Protection
AP2128 have 1.0V, 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, · Compatible with Low ESR Ceramic Capacitor:
3.3V, 3.9V, 4.2V, 4.75V, 5.2V fixed voltage versions
and 0.8V to 5.5V adjustable voltage version.
1µF for CIN and COUT
· Excellent Line/Load Regulation
AP2128 series are available in SOT-23-5 package.
· Soft Start Time: 50µs
· Auto Discharge Resistance: RDS(ON)=60Ω
Applications
· Datacom
· Notebook Computers
· Mother Board
