3.3 Subregulator

The TMP126 is powered onboard from the TLV700 LDO (U1). The onboard SN74LVC will perform any necessary level shifting of the SPI lines between the external power source and the TMP126EVM controller. When power is supplied to the TMP126 using either method, the green LED D3 will illuminate.
