Product Brief

AS1353, AS1356

Linear Low-Dropout 150mA Voltage Regulators

1 General Description

2 Key Features

ꢀ

Ultra-Low Dropout Voltage: 40mV @ 100mA load

The AS1353/AS1356 are high-performance, fixed-volt-

age linear LDOs designed for use with capacitors of 1 to

10µF. The devices can deliver superior performance

even under low dropout conditions when the power tran-

sistor operates in linear mode.

Output Voltage Range: +1.5 to +3.6V (100mV steps)

Max Output Current: 150mA

The integrated P-channel MOSFET output allows the

devices to maintain a low supply-current at loads of up

to150mA. A shutdown mode includes logic-controlled

circuitry which reduces shutdown current to less than

1µA (max).

Output Voltage Accuracy: ±1%

Low Shutdown Current: 1µA

High PSRR: 60dB at 100Hz

Integrated over-temperature and over-current protec-

tion circuitry switches the devices off in case of thermal

overload or output short-circuit conditions.

Integrated Overtemperature/Overcurrent Protection

Reverse-Battery Protection (AS1353/AS1356)

Power-OK Output (AS1356)

The AS1353/AS1356 are optimized for low equivalent-

series resistance (ESR) output capacitors. Additionally,

all devices contain reversed battery protection which dis-

connects the internal circuitry and parasitic diodes if the

battery is connected incorrectly.

Minimal External Components Required

Operating Temperature Range: -40 to +85°C

5-pin SOT23 Package

The AS1356 also features power-OK circuitry which can

be used to monitor output regulation.

All devices also feature an integrated error amplifier and

built-in 1.25V reference, and output current is limited

(380mA typ) via the on-chip current limiting circuitry.

Multiple output voltages are available as standard prod-

ucts: 3.6, 3.3, 3.0, 2.7, 2.5, or 1.5V. All devices are avail-

able in a 5-pin SOT23 package.

3 Applications

The devices are ideal for powering cordless and mobile

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

handheld computers, digital cameras, and any other

hand-held and/or battery-powered device.
