[MRCA] PRC-64 Battery Pack - need low power regulator

[B. Smith]

Rich, just a standard a LM-317 would work fb.

What kind of battery did you order from that company (Zbattery)

I have built several "battery trays" for the PRC-47/Delco  5300.And always 
had a dedicated   supply for the receiver, usually  4.5 volts.

The batteries from ZBattery finally arrived and they are a nice fit for the 
PRC-64 battery holder. I need to drop one 12V SLA stick output down to 4VDC 
to supply the receiver.

Does anyone have a recommendation for an adjustable low power voltage 
regulator that will provide a 4V regulated DC output from one of the 12V SLA 
sticks?

Some folks have used series diodes, zeners, and of course there is the 
wonderfully quaint dropping resistor. I'd hoped to be able to provide a 
little more elegent solution to the problem of getting 4V DC for the 
receiver on the 64.

Suggestions?
