AAT2505 - Step-Down Converter/Linear Regulator

General Description

The AAT2505 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 cell lithium-ion / polymer batteries.

Key Features

  • include low quiescent current, low dropout voltage, and a Power-OK (POK) open drain output signaling when VOUT is in regulation. The 600mA step-down converter is designed to operate with 1.4MHz of switching frequency, minimizing external component size and cost while maintaining a low 27µA no load quiescent current. AAT2505 Features.
  • SystemPower™.
  • VIN Range: 2.7V to 5.5V 300mA LDO.
  • 400mV Dropout Voltage at 300mA.
  • H.

Dual Channel, Step-Down Converter/Linear Regulator General Description The AAT2505 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 cell lithium-ion / polymer batteries. The LDO has an independent input pin and is capable of delivering up to 300mA of current. 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, low dropout voltage, and a Power-OK (POK) open drain output signaling when VOUT is in regulation.
