Re: Save power supply voltage for uBitx V6

once the battery (3*3.7V)  12.8 or so on full charge , falls to 11V, how do you expect the 78H12 to regulate and deliver?
The Vin /Vout differential for 78H12 is 2.5 to 3V. Don't you feel a Low drop regulator is better, like LT1083adjutable with 7.5 amps deliverable load.   Voltage differential is hardly 1V.
