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.
