NCP785A/D

NCP785A

Wide Input Voltage Range

10mA Ultra-Low Iq, High

PSRR Linear Regulator

The NCP785A 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 10 mA.

Ideal for high input voltage applications such as industrial and home

metering, home appliances. The NCP785A family offers

±5% initial

accuracy, extremely high−power supply rejection ratio and ultra−low

quiescent current. The NCP785A is optimized for high−voltage line

and load transients, making this part ideal for harsh environment

applications.

The NCP785A is offered in fixed output voltage options 3.3 V,

5.0 V, 12 V and 15 V.

SOT−89 package offers good thermal performance and help to

minimize the solution size.

Features

DC: Up to 450 V

AC: 85 V to 260 V (half−wave rectifier and 2.2
