10 mA Ultra-Low Iq, High
PSRR Linear Regulator with
Enable Pin
http://onsemi.com
The NCP785B 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 NCP785B LDO offers ±5% initial
accuracy, extremely high−power supply rejection ratio and ultra−low
quiescent current. It is optimized for high−voltage operations, making
them ideal for harsh environment applications.
The device is offered in fixed output voltages 3.3 V, 5.0 V, 12 V and
15 V. NCP785B has an Enable pin with internal pull up which allows
for easy output voltage ON/OFF control. SOT−223 package option
provides good thermal performance as well as helps to minimize the
overall solution size.
