AAT2557 500mA Battery Charger and 300mA LDO Regulator

The AAT2557 is a fully integrated 500mA battery charger and a 300mA low dropout (LDO) linear regulator. The input voltage range is 4V to 6.5V for the battery charger and 2.7V to 5.5V for the linear regulator, making it ideal for applications operating with single-cell lithium-ion/ polymer batteries..

AAT2557 Features

* the device offers over-voltage, current limit, and thermal protection. The linear regulator is designed for fast transient response and good power supply ripple rejection. Capable of up to 300mA load current, it includes shortcircuit prot
