HI,
We are using 1.2V,3.3V and 5V and the load consumes 750mA current with the input DC at 7.5V,7AH battery / 9v, 1A from adapter. We are using LM1117(800mA) regulators for this.But we have a problem in this design.We are facing a overload problem and also the regulators gets more heat.So please give me the suggestions to solve this problem .I have attached our power supply schematic diagram (two files,we are tried both the types).
Best Regards,
Naveen
