1A LOW DROPOUT LINEAR REGULATOR

CURRENT MODE PWM CONTROLLER

General Description

The AZ1117 is a series of low dropout three-terminal

regulators with a dropout of 1.15V at 1A output cur-

rent.

The AZ1117 series provides current limiting and ther-

mal shutdown. Its circuit includes a trimmed bandgap

reference to assure output voltage accuracy to be

within 1% for 1.5V, 1.8V, 2.5V, 2.85V, 3.3V, 5.0V and

adjustable versions or 2% for 1.2V version. Current

limit is trimmed to ensure specified output current and

controlled short-circuit current. On-chip thermal shut-

down provides protection against any combination of

overload and ambient temperature that would create

excessive junction temperature.

The AZ1117 has an adjustable version, that can pro-

vide the output voltage from 1.25V to 12V with only 2

external resistors.

The AZ1117 series is available in the industry standard

SOT-223, SOT-89-3, TO-220-3, TO-252-2 and TO-

263-3 power packages.
