NCP785 Overview

Wide Input Voltage Range PSRR Linear Regulator

NCP785
Product Preview
Wide Input Voltage Range
5 mA Ultra-Low Iq, High
PSRR Linear Regulator
The NCP785 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 5 mA.
Ideal for high input voltage applications such as industrial and home
metering, home appliances. The NCP785 family offers
±5%
initial
accuracy, extremely high−power supply rejection ratio and ultra−low
quiescent current. The NCP785 family is optimized for high−voltage
line and load transients, making them ideal for harsh environment
applications.
The NCP785 is offered in fixed output voltage options 3.3 V and
5.0 V.
SOT−223 and SOT−89 packages offer good thermal performance
and help to minimize the overall solution size.
