| CM1117A 600mA LOW DROPOUT VOLTAGE REGULATOR GENERAL DESCRIPTION The CM1117A is a series of low dropout three-terminal regulators with a dropout of 1.1V at 600mA output current. These products have been optimized for low voltage where transient response and minimum input voltage are critical. These CM1117A provide current limit and thermal shutdown. Its circuit includes a trimmed band-gap reference to assure output voltage accuracy to be within FEATURES Low Dropout Voltage: 1.1V at 600mA output Current. Output Noise from 10Hz to 10KHz: 0.003% PSRR at Io = 300mA and f =120Hz: 75dB Output Voltage Accuracy: 1% On-Chip Thermal Shutdown Maximum Quiescent Current: IQMAX =5mA ESD (Human Body Model): 3.5KV Operation Junction Temperature -40 to 125 1%. On -chip thermal 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.
