Output of regulator #1. Drives the gate of an N-channel MOSFET to maintain 1.818V/
2.525V.
Regulator #1 Sense input. Use as a remote sense to the source of the N-channel MOSFET
(Output 1).
Active high enable control with internal pullup. Output of regulator #1 turns off when EN1 is
taken low.
Ground
