CM1117A

600mA L^OWDROPOUT VOLTAGE REGULATOR

GENERAL DESCRIPTION

FEATURES

The CM1117A is a series of low dropout three-terminal

regulators with a dropout of 1.1V at 600mA output current.

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%

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.

On-Chip Thermal Shutdown

Maximum Quiescent Current: I_QMAX=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.
