NCP781 Datasheet, PDF (1/14 Pages) ON Semiconductor – 150 V, 100mA Very High Voltage Linear Regulator

NCP781
150 V, 100 mA Very High
Voltage Linear Regulator
The NCP781 is a very high−voltage tolerant linear regulator that
offers the benefits of thermally enhanced DFN6 3.3 x 3.3 package and
is able to withstand continuous DC or transient input voltages up to
150 V. The device is stable with small 0.1 mF Ceramic Output
Capacitors which allows smaller PCB design at space constraining
applications. The devices features enable pin compatible with
standard CMOS logic.
Features
• Wide Input Voltage Range: 6 V to 150 V
• Output Voltage Versions:
Fixed: 3.3 V, 5 V, 15 V
Adjustable: from 1.23 V up to 15 V
• ±2.5% Accuracy at Room Temperature
• Very Low Quiescent Current of Typ. 25 mA
• Standby Current: 1 mA
• Stable with a 0.1 mF Ceramic Output Capacitor
• Very High PSRR: 83/56 dB@1/100 kHz
• Thermal Shutdown and Current Limit Protection
• Available in Thermally Enhanced DFN6 3.3 x 3.3, 0.65P Package
• Ideal for Harsh Environments
• These are Pb−free Devices
Typical Applications
• Telecom, Industrial
• Bias Power Supplies, Led Lighting
