At max maybe 300ma. Any recommendations on a shunt regulator, my searches didn't turn up much.

Just checked out the TL431, seems just like what I need. I'm gonna draw up a circuit and post back in a bit.

Looking at the TL431 it seems it can only sink...
I'm powering an MCU through either 4 alkaline/Ni-MH or 2 Li-Ion cells. The maximum voltage the MCU can handle is 6V and the BOD level is set for 3V. When 2 Li-ion cells are used the input voltage will be ~7.4 volts and I'd like to regulate this voltage to prevent damage to the MCU. When the...
I'm building a battery powered device which, at maximum, will consume 3A at 3.8V. I'd like to have the option to use 3-4 alkaline/NI-MH batteries or 2-4 lithium ion batteries. The first revision of my circuit used a buck regulator, however, the bootstrap voltage was set by a 5V LDO, meaning I...
