600mA LOW DROPOUT VOLTAGE REGULATOR
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 ± 1%. On –chip thermal
shutdown provides protection against any combination of
overload and ambient temperatures that would create
excessive junction temperatures.
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℃
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.
