Hello everyone,
Ive been trying to build a dc-to-dc step up circuit that uses two AA batteries (~3.4V) to power a 5V RFID reader unit.
I'm using a MCP1700-5002E but it doesn't seem to be working. Whatever I put in under 5V will be matched on the other side. For example, placing two AA batteries (~3.4V) at Vin will be ~3.4V at Vout. Placing 4xAA batteries (~6.2V) makes it 5V at the output.
What am I doing wrong? Aren't these MCP1700s supposed to step up the voltage to 5V?
Thanks
