1.2 Performance Specification Summary

A summary of the EVM performance specifications is provided in Table 1-2. Specifications are given for an input voltage of VIN = 12 V and an output voltage of 1.05 V, unless otherwise noted. The VIN and VCC input voltage pins are cnnected on the EVM using a 0-Ω resistor (R9). The ambient temperature is 25°C for all measurement, unless otherwise noted.
