CM1117A 600mA LOW DROPOUT VOLTAGE REGULATOR GENERAL DESCRIPTION FEATURES The CM1117A is a series of low dropout three-terminal Low Dropout Voltage: 1.1V at 600mA output Current. regulators with a dropout of 1.1V at 600mA output current. Output Noise from 10Hz to 10KHz: 0.003% PSRR at Io = 300mA and f =120Hz: 75dB These products have been optimized for low voltage where Output Voltage Accuracy: transient response and minimum input voltage are critical. On-Chip Thermal Shutdown ± 1% These CM1117A provide current limit and thermal shutdown. Maximum Quiescent Current: IQMAX =5mA Its circuit includes a trimmed band-gap reference to assure ESD (Human Body Model): 3.5KV Operation Junction Temperature –40 to 125℃ ± 1%. On –chip thermal output voltage accuracy to be within shutdown provides protection against any combination of overload and ambient temperatures that would create excessive junction temperatures. The CM1117A is available in 2.5V and 3.3V versions. The fixed versions integrate the adjust resistors. It is also available in an adjustable version which can set the output voltage with two external resistors.
