onsemi NCP781 VREG

Linear voltage regulator, 100 mA, 150 V

The NCP781 is a very high-voltage tolerant linear regulator, supporting continuous input voltages up to 150 V, and is offered in a thermally enhanced DFN6 package.

The part is capable of delivering up to 100 mA of output current and offers ±3% accuracy over the full operating temperature range. It offers stable operation with 0.1 μF ceramic output capacitors, which allows smaller PCB design in space-constrained applications.
