Batter Charger Circuit
I have some basic doubts reg power supply requirements for a GPS Receiver. It needs 3.3 V regulated Power supply. Im currently using a 3.3V 300 mAh battery.
Is there a way to generate 3.3 V Regulated supply as easy as using 7805 for 5 V supply. I even looked at MAX 756 IC but it is not available near my place.
Can anyone suggest an alternative?
Is it possible to supply +5V and -5 V (i mean enabling or disabling a voltage inverter. pls include a voltage inverter circuit link if u have one) from a microcontroller pin.

One more doubt.
Can anyone help me in designing a charging circuit for a 3.6 V 300 mAh battery?
