NCV47551: Low Noise LDO Regulator with Adjustable Current Limit and
Voltage
For complete documentation, see the data sheet
Product Description
The NCV47551 is a low noise low 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.
