GENERAL DESCRIPTION

The CJU1117B-XXX is a series of low dropout three-terminal regulators with a dropout of 1.3V at 1A

output current.

The CJU1117B-XXX series provides current limiting and thermal shutdown. Its circuit includes a

trimmed bandage. reference to assure output voltage accuracy to be within 1.5%. 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 CJU1117B-XXX has an adjustable version, that can provide the output voltage from 1.25V to 12V

with only 2 external resistors.

APPLICATIONS
