3.8 EVM Operating Conditions

The TMP126EVM power is supplied through the USB connector. The LDO (U1) converts the 5V from the USB to 3.3V used by the TMP126 and the MSP430. The EVM may be directly inserted into a USB port on a PC or laptop, or may be connected to the latter using an appropriate USB cable.

The controller and device sides of the EVM have different temperature limits as shown in Table 3-2. These are set by the onboard MSP430F5528 and the TMP126 ICs on the controller and breakout portions respectively.
