Description

Diff Probe Power Supply (Discrete)

This is a companion Daughter Board power supply for the new 10MHz and 1MHz differential probes listed in Shared Projects.

This is a voltage regulator composed of discrete parts and can be configured to supply the 15V input to the probes.

It has an optional over-voltage protection section that can be omitted.

The input to the regulator can be a USB-C PD Trigger Board, set for a 20V output.

With a 20V input, the circuit can be further simplified by using the 20V schematic.

This board will be glued together with the USB-C Trigger Board and will fit inside the differential probe enclosure.
