General Description Features
The CP1117 is a series of low dropout three-terminal Low dropout voltage: 1.2V at 1A output current
regulators with a dropout of 1.2V at 1A output current. Trimmed current limit
The CP1117 has an adjustable version, that can On-chip thermal shutdown
provide the output voltage from 1.25V to 12V with only 2 Three-terminal adjustable of fixed 1.5V, 1.8V,
external resistors. 2.5V, 3.3V, 5V
The CP1117 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
Applications
output current and controlled short-circuit current.
Onchip thermal shutdown provides protection against any PC Motherboard
combination of overload and ambient temperature that LCD Monitor
would create excessive junction temperature. Graphic Card
