NCP785A: Linear Regulator, Ultra-Wide Input Voltage Range, 450 V, 10 mA

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. The NCP785A is very well suited for harsh environmental conditions. The NCP785A is offered with fixed output voltages: 3.3 V, 5.0 V, 12 V, 15 V. SOT−89 package offers good thermal performance and very small PCB size.
