ZCC2785 (500V线性稳压器芯片，替代NCP785)

Siweidianzi

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
