GENERAL DESCRIPTION

The CJT1117B-XXX is a series of low dropout three-terminal regulators with a dropout of 1.15V(typ.)

at 1A output current.

The CJT1117B-XXX series provides current limiting and thermal shutdown. Its circuit includes a

trimmed bandgap. 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 CJT1117B-XXX has an adjustable version, that can provide the output voltage from 1.25V to 5V with

only 2 external resistors.
