NCP785A
Wide Input Voltage Range
10âmA Ultra-Low Iq, High
PSRR Linear Regulator
The NCP785A is a highâperformance 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 highâpower supply rejection ratio and ultraâlow
quiescent current. The NCP785A is optimized for highâvoltage 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.
SOTâ89 package offers good thermal performance and help to
minimize the solution size.
