AAT1117
1 Amp Linear Regulator
General Description
The AAT1117 is a Positive Linear Regulator
designed to deliver 1 amp. It features adjustable
or fixed output voltages and excellent
performance over line and load variations. The
device is able to protect itself and the load from
short circuit conditions with integrated current
limiting circuitry. Thermal shutdown is activated
to prevent damage under extreme conditions.
The AAT1117 is available in surface mount SOT-
223 or TO-252 (DPAK), and through-hole TO-220
packages.

Function
For the fixed version of AAT1117, pin 1 is the ground connection. For the adjustable
version, this pin is the ADJ pin. See detailed description for further information
regarding configurations.
Output pin – should be decoupled with 10µF tantalum or greater output capacitor.
Input pin - should be decoupled with 10µF tantalum or greater capacitor.
