How much current can MicroStamp11s on-board regulator provide?
The 5-Volt regulator built into MicroStamp11 can supply 100 mA current if powered by a 6 Volt source. The limit is affected by operating temperature, so if the unit is running significantly above room temperature, the maximum current it can supply will be reduced. The amount it can supply will also be reduced if you use a higher input voltage. This is because the regulator drops the voltage to 5 Volts by dissipating the excess voltage as heat. MicroStamp11 draws approximately 15 mA in RUN mode, leaving 85 mA for use with other circuitry via the +5VDC pin and the I/O pins.
