Abstract:
A circuit for use with highly sensitive power application such as in-vacuum electronics or the like. This design is rated at up to +/- 26VDC at +/- 1ADC. The circuit protects against reverse polarity, missing supply rail, and provides a soft start to protect sensitive circuitry.

Notes and Changes:
Version 3 - Noticed C8 is actually in backwards on the version 2 schematic and circuit board. Version 3 correctly depicts the capacitor as it should be, but the board is still wrong. The board should be fixed prior to making more of these. Consider addition of e-fuse circuitry for a complete solution.
