The built in 5-volt regulator on the BASIC Stamp can supply 50 mA of current if powered by a 12-volt source. The BASIC Stamp I consumes 2 mA in running mode and the BASIC Stamp II consumes 7 mA. This leaves 48 mA and 43 mA respectively for use with other circuitry via the VDD pin and the I/ O pins.
