8.1.8 PSRR

Depending on the application, there may be a significant amount of high frequency noise on the power supply line. If high frequency noise (>100 KHz) is present, the user can switch to a 1-μF bypass capacitor to provide additional filtering on the power supply line. Increasing the bypass capacitance or choosing a capacitor with a lower ESR across frequency will improve PSRR performance.

An additional power supply consideration is line regulation. For the ISOTMP35, line regulation refers to the change in output temperature with changing power supply. Figure 6-6 shows that, across the entire environment temperature range, ISOTMP35 maintains a steady amount change in temperature across VDD.
