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
capability.
·
·
·
·
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 provides current limiting and thermal shutdown. Its circuit includes a trimmed bandgap
reference to assure output voltage accuracy to be
within 1%. Current limit is trimmed to ensure specified
output current and controlled short-circuit current. Onchip thermal limiting provides protection against any
combination of overload and ambient temperature that
would create excessive junction temperature.
The AZ1117 series is available in the industry standard SOT-223, SOT-89, TO-220 , TO-252 and TO-263
power packages.
