GENERAL DESCRIPTION
The CJA1117B-XXX is a series of low dropout three-terminal regulators with a dropout of 1.15V at
1A output current.
The CJA1117B-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 CJA1117B-XXX has an adjustable version, that can provide the output voltage from 1.25V to 5V with
only 2 external resistors.
APPLICATIONS
 PC Motherboard
 LCD Monitor
 Graphic Card
 DVD-Video Player
 NIC/Switch
 Telecom Modem
 ADSL Modem
 Printer and other peripheral Equipment
