1A LOW DROPOUT LINEAR REGULATOR

Description

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, which can provide the output

voltage from 1.25V to 12V with only 2 external resistors.

The AZ1117 series is available in the industry standard SOT223,

SOT89, TO220-3, TO252-2 (3), TO252-2 (4), TO252-2 (5) and TO263

power packages.
