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
" H" U- w' C: _  M, Z( r10 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
