General Description
The G1117-XX is a low dropout linear regulator with a dropout of 1.3V at 1A of load current. It is available in four fixed voltage: 1.5V, 1.8V, 2.5V, 3.3 and 3.5V versions.
The G1117-XX provides over temperature and over current protection circuits to prevent it from being damaged by abnormal operating conditions.
The G1117-XX is available in SOT-223 packages. A minimum of 10µF tantalum electrolytic capacitor is required at the output to improve the transient response and stability.

Features
■ Available in 1.5V, 1.8V, 2.5V, 3.3V,3.5V Version
■ Space Saving SOT-223 Package
■ Internal Short Circuit Current Limiting
■ Internal Over Temperature Protection
■ Output Current in Excess of 1A

Applications
■ „ Post Regulation for Switching DC/DC Converter
■ „ High Efficiency Linear Regulator
„■ Battery Charger
■ „ Battery Powered Instrumentation
■ „ Motherboard
