2.2 Subregulator

The switch S1 enables and disables the onboard 3.3-V regulator: U8. When the subregulator is enabled, the green LED D3 illuminates. The subregulator must be enabled for normal operation of TMP1826EVM. It is possible to supply other voltages at the 3P3V pin when the subregulator is disabled.
