Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Conditions are
conditions under which the device functions but the specifications might not be guaranteed. For guaranteed specifications
and test conditions see the Electrical Characteristics.
The maximum power dissipation is a function of the maximum junction temperature, TJmax ; total thermal resistance, θJA,
and ambient temperature TA. The maximum allowable power dissipation at any ambient temperature is Tjmax-TA / θJA. If
this dissipation is exceeded, the die temperature will rise above 150°C and IC will go into thermal shutdown. For the
G1117 in SOT-223 package; θJA is 116°C/W (See recommend minimum footprint).
Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
The type of output capacitor should be tantalum or aluminum.

General Description
The G1117 is a low dropout linear regulator with a dropout of 1.2V at 800mA of load current and 1.3V at 1A of load current. It is available in an adjustable version, which can set the output from 1.25V to 5V with only two external resistors.
The G1117 provides over temperature and over current protection circuits to prevent it from being damaged by abnormal operating conditions.
The G1117 is available in TO-252, SOT-223 and TO-92 packages. A minimum of 10μF tantalum electrolytic capacitor is required at the output to improve the transient response and stability.

Features
■ Available in adjust version
■ Space saving TO-252, SOT-223 and TO-92 package
■ Internal short circuit current limiting
■ Internal over temperature protection
■ Output current in excess of 1A
■ Output current in excess of 100mA with TO-92 package

Applications
■ Post regulation for switching DC/DC converter
■ High efficiency linear regulator
■ Battery charger
■ Battery powered instrumentation
■ Motherboard
