Logic Level of Power LDO's should be 3V3. #19

Power enable inputs on the 2V8 and 1V2 LDO's are constrained to VCC+/-0.3V.

Texas Instruments has a pin compatible part (TPS7A20) that has a more tolerant input. Alternativley the ATtiny10 could be run from 3V3 (and programmed off-board)

Migrated to TPS7A20 from Rev004, testing required to validate correct behaviour.
