CP1117 Low Dropout Linear Regulator General Description Features 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 z Low dropout voltage: 1.2V at 1A output current z Trimmed current limit z On-chip thermal shutdown z Three-terminal adjustable of fixed 1.5V, 1.8V, 2.5V, 3.3V, 5V z Operation junction temp.: 0℃ to 125℃ within 1%. Current limit is trimmed to ensure specified Applications 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.
