The LDO Board
Introduction
The LDO board or "Low Drop Out" board is essentially a break out board for linear regulators. It supports both TO-92 and TO-220 packages, so for lower current draw applications, the MCP1702 linear regulator can be placed, but for heavier loads, something like the TC1262 can be used. There's also a standard barrel jack on the board for power entry. The board works nicely with the Platform Board

Parts
It is up to you to order the parts. The list can be downloaded **HERE**. This can be directly uploaded into Digikey if you'd like.
Assembly
Soldering the boards together is pretty straightforward - just make sure the electrolytic capacitors go in the right way. The board has + marking indicating polarity.
There are two options for assembly, here is with a TO92 regulator. Note the red arrow near the switch pins. These two pins can be used to disconnect the VIN to the regulator. If not needed, just jumper them out. If the voltage input to the board needs to be monitored, this is where it can be measured.
And the TO220 type package - see the BOM for part numbers. Note any, TO92 or TO220 package would work as long as the same pinout is followed. WARNING: Not all regulators use the same pinout!
