Wide Input Voltage Range
5 mA Ultra-Low Iq, High
PSRR Linear Regulator
The NCP785 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 5 mA.
Ideal for high input voltage applications such as industrial and home
metering, home appliances. The NCP785 family offers ±5% initial
accuracy, extremely high−power supply rejection ratio and ultra−low
quiescent current. The NCP785 family is optimized for high−voltage
line and load transients, making them ideal for harsh environment
applications.
The NCP785 is offered in fixed output voltage options 3.3 V and
5.0 V.
SOT−223 and SOT−89 packages offer good thermal performance
and help to minimize the overall 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)
• 5 mA Guaranteed Output Current
• Ultra Low Quiescent Current: Typ. 6 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, SOT−223 Packages
• This is a Pb−Free Device
Typical Applications
• Industrial Applications, Home Appliances
• Home Metering / Network Application
• Off−line Power Supplies
