NCP785A
NCP785A
Linear Regulator - Wide
Input Voltage Range,
Ultra-Low Iq, High PSRR
10 mA
The NCP785A is a highperformance 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 highpower supply rejection ratio and ultralow
quiescent current. The NCP785A is optimized for highvoltage 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.
SOT89 package offers good thermal performance and help to
minimize the solution size.
