1A LOW DROPOUT LINEAR REGULATOR
GENERAL DESCRIPTION
The 1117 is a series of low dropout three-terminal egulators with a dropout of 1.15V at 1A output current.
The 1117 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. On-chip thermal shutdown provides protection against any
combination of overload and ambient temperature that would create excessive junction temperature.
The 1117 has an adjustable version, that can provide the output voltage from 1.25V to 5V with only 2
external resistors.
The 1117 series is available in the industry standard SOT-223,SOT-89,TO-220,TO-252 and TO-263 power
packages.
