NCV47821  
3.3 V to 20 V Adjustable Dual  
LDO with Adjustable Current  
Limit and Diagnostic Features  
The NCV47821 dual channel LDO regulator with 200 mA per  
channel is designed for use in harsh automotive environments. The  
device has a high peak input voltage tolerance and reverse input voltage,  
reverse bias, overcurrent and overtemperature protections. The  
integrated current sense feature (adjustable by resistor connected to  
CSO pin for each channel) provides diagnosis and system protection  
functionality. The CSO pin output current creates voltage drop across  
CSO resistor which is proportional to output current of each channel.  
Extended diagnostic features in OFF state are also available and  
controlled by dedicated input and output pins.
