Alternatively NCP785A ZCC2785 linear regulator
ZCC 2785 is a high performance linear regulator provides a very wide range of input voltage up to 450 VDC, output current up to 10 mA. Suitable for industrial and household meter high input voltage applications, home appliances. ZCC 2785 series initial accuracy of ± 5%, a high power supply rejection ratio and ultra-low quiescent current. ZCC 2785 is optimized for high-voltage line and load transient, so that the member ideal for applications in harsh environments. ZCC 2785 provides a fixed output voltage options of 2.7V, 3.3V and 5.0V.
