3.3 Subregulator

Pins 1 and 2 of the 100-mil header J3 can be shorted with a jumper to supply 1.2-V power to the TMP114 from the onboard LDO (U1). Alternatively, the jumper between pins 1 and 2 can be removed, and pins 2 and 3 of J3 can be used to supply power to the onboard TMP114. The onboard level shifter will perform any necessary translation of the I2C lines between the external power source and the TMP114EVM controller. When power is supplied to the TMP114 using either method, the green LED D3 will illuminate.
