ZCC2785  
Wide Input Voltage Range 10_mA Ultra-Low Iq  
High PSRR Linear Regulator  
The ZCC2785 is a high−performance linear regulator, offering a very wide  
operating input voltage range of up to 450 V DC, with an output current of up to  
10 mA.  
Ideal for high input voltage applications such as industrial and home metering,  
home appliances. The ZCC2785 family offers ±5% initial accuracy, extremely  
high−power supply rejection ratio and ultra−low quiescent current. The  
ZCC2785 is optimized for high−voltage line and load transients, making this  
part ideal for harsh environment applications.  
The ZCC2785 is offered in fixed output voltage options 2.7V,3.3 V, and5.0 V.  
ESOP8 package offers good thermal performance and help to minimize the  
solution size.
