This is a simple +/-5V low-dropout regulator board designed to provide regulated +5V and -5V from two 6V rechargeable batteries, at up to 1A. === Design Files === * Schematic: [http://ohm.bu.edu/~vryoung/Voltage_Regulator/supply.sch supply.sch] [http://ohm.bu.edu/~hazen/Ahlen_Neutron/BatteryPower/supply_sch.pdf supply_sch.pdf] * PCB layout: [http://ohm.bu.edu/~vryoung/Voltage_Regulator/supply.pcb supply.pcb] [http://ohm.bu.edu/~hazen/Ahlen_Neutron/BatteryPower/supply_pcb.pdf supply_pcb.pdf] * Photo: [http://ohm.bu.edu/~hazen/Ahlen_Neutron/BatteryPower/IMG_0357.JPG IMG_0357.JPG] WARNING! Positive input trace on left side of the board shorts to the on/off switch which is grounded. Solution is to either solder the on/off switch slightly off the board, or to place a piece of non-conductive tape over the trace that runs under the switch.
