AS1371

400mA, Low Input Voltage, Low Quiescent Current LDO

1 General Description

2 Key Features

ꢀ

Ultra-Low Dropout Voltage: 20mV @ 100mA load

Operating Input Voltage Range: 1.2V to 3.6V

Output Voltages: 0.6V to 3.3V in 50mV steps

Max. Output Current: 400mA

The AS1371 low input voltage, positive voltage regulator

is designed to deliver up to 400mA while consuming

typically only 15µA of quiescent current. The device

operates from input voltages of 1.2V to 3.6V, and is

available in fixed output voltages between 0.6V and

3.3V (programmable in 50mV steps).

Output Voltage Accuracy: ±1%

Operation at the full 400mA load current is dependent

upon the maximum power dissipation available from

package and environment.

Low Shutdown Current: 10nA

Low Quiescent Current: 50µA @ max load

Integrated Overtemperature/Overcurrent Protection

Under-Voltage Lockout Feature

The low input voltage and ultra-low dropout voltage

(20mV @ 100mA load and 80mV @ 400mA load)

supports single primary cell operation in small

applications, when operated with minimum input-to-

output voltage differentials. In addition, the regulator

Power-OK and Low Battery Detection

Sense Input Option

provides

a power management life extension by

operating from pre-existing 1.8V and 2.5V outputs to

provide low output voltages for new generation portable

processor cores.

Minimal External Components Required

Operating Temperature Range: -40°C to +85°C

6-pin 2x2 TDFN Package

The device features stable output voltage with ceramic

capacitors down to a value of 1µF, strict output voltage

regulation tolerances (±1%), and good line- and load-

regulation.

3 Applications

The devices are ideal for powering cordless and mobile

phones, MP3 players, CD and DVD players, PDAs,

hand-held computers, digital cameras, and any other

hand-held and/or battery-powered device.

The AS1371 is available in a 6-pin 2x2 TDFN package

and is qualified for -40°C to +85°C operation.
