AAT2500 - Step-Down Converter/LDO Regulator

General Description

The AAT2500 is a member of AnalogicTech's Total Power Management IC™ (TPMIC™) product family.

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.

Key Features

  • include low quiescent current and a low dropout voltage. The 400mA step-down converter is designed to minimize external component size and cost while maintaining a low 25µA no load quiescent current. Peak current mode control with internal compensation provides a stable converter with a low equivalent series resistance (ESR) ceramic output capacitor for extremely low output ripple. For maximum battery life, the step-down converter increases to 100% duty cycle and has a typical 180mV dropout volt.

1MHz Step-Down Converter/LDO Regulator General Description The AAT2500 is a member of AnalogicTech's Total Power Management IC™ (TPMIC™) product family. 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. 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 features include low quiescent current and a low dropout voltage. The 400mA step-down converter is designed to minimize external component size and cost while maintaining a low 25µA no load quiescent current.
