NCP785A/D
NCP785A
Wide Input Voltage Range
10mA 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.
