NCP786A Linear Regulator - Wide Input Voltage Range, Ultra-Low Iq, High PSRR, Adjustable Output Voltage www.onsemi.com 10 mA The NCP786A is highperformance linear regulator, offering a very MARKING wide operating input voltage range of up to 450 V DC, with an output DIAGRAM current of up to 10 mA. Ideal for high input voltage applications such as industrial and home metering, home appliances. The NCP786A 786A family offers 3% initial accuracy, extremely highpower supply XXX rejection ratio and ultralow quiescent current. The NCP786A family ALLYYWW DFN6 5x6 is optimized for highvoltage line and load transients, making them ST SUFFIX ideal for harsh environment applications. The output voltage can be set CASE 506DV (Top View) by resistor divider in range from 1.27 V up to 15 V.
