1A LOW DROPOUT LINEAR REGULATOR
GENERAL DESCRIPTION
The CJ1117 is a series of low dropout three-terminal regulators with a dropout of 1.15V at 1A output current.
The CJ1117 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 CJ1117 has an adjustable version, that can provide the output voltage from 1.25V to 12V with only 2
external resistors.
The CJ1117 series is available in the industry standard SOT-223,SOT-89,TO-220,TO-252 and TO-263 power
packages.
