CJA1117B-5.0 Datasheet, PDF (1/4 Pages) ZP Semiconductor – 1A LOW DROPOUT LINEAR REGULATOR

CJA1117B-XXX
1A LOW DROPOUT LINEAR REGULATOR
GENERAL DESCRIPTION
The CJA1117B-XXX is a series of low dropout three-terminal regulators with a dropout of 1.15V(typ.)
at 1A output current.
The CJA1117B-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 CJA1117B-XXX has an adjustable version, that can provide the output voltage from 1.25V to 5V with
only 2 external resistors.
