1A LOW DROPOUT LINEAR REGULATOR
AZ1117
General Description
Features
The AZ1117 is a series of low dropout three-terminal
regulators with a dropout of 1.15V at 1A output current.
·
·
·
·
The AZ1117 series provides current limiting and thermal 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 shutdown provides protection against any combination of
overload and ambient temperature that would create
excessive junction temperature.

The AZ1117 has an adjustable version, that can provide 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, TO-220-3, TO-252-2 (1), TO-252-2
(2), TO-252-2 (3), TO-252-2 (4) and TO-263-3 power
packages.
