ZCC2785替代NCP785

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.
package offers good thermal performance and help to
minimize the solution size.
