1 / 10 page © Semiconductor Components Industries, LLC, 2014 December, 2014 − Rev. 2 1 Publication Order Number: NCP785A/D NCP785A Wide Input Voltage Range 10mA 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. Features • Wide Input Voltage Range: DC: Up to 450 V AC: 85 V to 260 V (half−wave rectifier and 2.2 mF capacitor) • 10 mA Guaranteed Output Current • Ultra Low Quiescent Current: Typ. 10 mA (VOUT ≤ 5 V) • ±5% Accuracy Over Full Load, Line and Temperature Variations • Ultra−high PSRR: 70 dB at 60 Hz, 90 dB at 100 kHz • Stable with Ceramic Output Capacitor 22 mF MLCC • Thermal Shutdown and Current Limit Protection • Available in Thermally Enhanced SOT89−3 Package • This is a Pb−Free Device Typical Applications • Industrial Applications, Home Appliances • Home Metering / Network Application • Off−line Power Supplies Figure 1.
