AAT2506

1MHz Step-Down Converter/LDO Regulator

™

SystemPower

General Description

Features

The AAT2506 is a member of AnalogicTech's Total

Power Management IC™ (TPMIC™) product fam-

ily. It is a low dropout (LDO) linear regulator and a

step-down converter with an input voltage range of

2.7V to 5.5V, making it ideal for applications with

single lithium-ion/polymer batteries.

•

V_INRange: 2.7V to 5.5V

V_OUTRange: 0.6V to V_IN

300mA LDO Current Output

400mV LDO Dropout Voltage at 300mA

High Output Accuracy: ±1.5%

Fast LDO Line / Load Transient Response

600mA, 97% Efficiency Step-Down Converter

Fast Turn-On Time (100µs Typical)

25µA No Load Quiescent Current for Step-

Down Converter

The LDO has an independent input and is capable

of delivering up to 300mA. The linear regulator has

been designed for high-speed turn-on and turn-off

performance, fast transient response, and good

power supply rejection ratio (PSRR). Other fea-

tures include low quiescent current and a low

dropout voltage.

Available in TDFN33-12 Package

-40°C to +85°C Temperature Range

The AAT2506 is available in either a fixed version

with internal feedback or a programmable version

with external feedback resistors. It can deliver

600mA of load current while maintaining a low

25µA no load quiescent current. The 1MHz switch-

ing frequency minimizes the size of external com-

ponents while keeping switching losses low. The

AAT2506 feedback and control delivers excellent

load regulation and transient response with a small

output inductor and capacitor.

Applications

•

Cellular Phones

Digital Cameras

Handheld Instruments

Microprocessor/DSP Core/IO Power

PDAs and Handheld Computers

Portable Media Players

The AAT2506 is designed to maintain high efficien-

cy throughout the operating range, which is critical

for portable applications.

The AAT2506 is available in a 12-pin TDFN33

package, and is rated over a temperature range of

-40°C to +85°C.
