Description
Low Dropout Linear Regulator
Manufacturer
Ceramate Technical Company
Datasheet
General Description
The CP1117 is a series of low dropout three-terminal
regulators with a dropout of 1.2V at 1A output current.
The CP1117 has an adjustable version, that can
provide the output voltage from 1.25V to 12V with only 2
external resistors.
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
output current and controlled short-circuit current.
Onchip thermal shutdown provides protection against any
combination of overload and ambient temperature that
would create excessive junction temperature.
The CP1117 eries is available in the industry
standard SOT-223 power package
