Linear Voltage Regulator, 10 mA, 450 V, Ultra-Low Iq, High PSRR

Favorite

Overview

The NCP785A is a high-performance >10mA linear regulator, offering a verywide 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 homeautomation, smart metering, home appliances. The NCP785A offers ±5% of output voltageaccuracy, extremely high power supply rejection ratio and ultra lowquiescent 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 performanceand very small PCB size.
