onsemi NCP785AH50T1G, 1 Linear Voltage, Voltage Regulator 10.5mA, 5 V 3+Tab-Pin, SOT

The NCP785A is a high-performance >10mA linear regulator, offering a very wide operating input voltage range of up to 450 V DC operating and 700V DC maximum. It is an ideal choice for high input voltage applications such as industrial and home automation, smart metering, home appliances. The NCP785A offers ±5% of output voltage accuracy, extremely high power supply rejection ratio and ultra low quiescent current of typ. 15μA.

Operating Input Voltage: Up to 450 VDC
PSRR: 80 dB at 120 Hz
Quiescent Current: 15μA Typical
Allows for direct AC mains connection
Effectively reduces the input ripple
Greatly reduces the no-load power consumption
Ideally suited for space constrained applications
