Linear Regulator - Wide Input Voltage Range, Ultra-Low Iq, High PSRR, Adjustable Output Voltage 5 mA www.onsemi.com NCP786L The NCP786L 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 5 mA. Ideal for high input voltage applications such as industrial and home metering, home appliances. The NCP786L family 4 offers 5% initial accuracy, extremely highpower supply rejection AYW ratio and ultralow quiescent current. The NCP786L family is SOT223 XXXXX S SUFFIX optimized for highvoltage line and load transients, making them ideal CASE 318E for harsh environment applications. The output voltage can be set by 1 23 resistor divider in range from 1.27 V up to 15 V.
