NCV47711
5 V to 20 V Adjustable LDO
with Adjustable Current
Limit and 3.3 V Logic
Compatible Enable Input
The NCV47711 is a 350 mA output current integrated low dropout
regulator designed for use in harsh automotive environments. It
includes wide operating temperature and input voltage ranges. The
device is offered with adjustable voltage versions available in 3%
output voltage accuracy. It has a high peak input voltage tolerance and
reverse input voltage protection. It also provides overcurrent
protection, overtemperature protection and enable for control of the
state of the output voltage. The integrated current sense feature
provides diagnosis and system protection functionality. The current
limit of the device is adjustable by resistor connected to CSO pin.
Voltage on CSO pin is proportional to output current.
