300mA

Adjustable output voltage and MODE select

At room temperature, the LMR36503MSCEEVM can support the full 300mA load at the maximum input voltage of 65V. At higher temperatures, such as 150°C ambient, the input voltage needs to be derated to a maximum of 20V to prevent the IC from entering thermal shutdown. At a input voltage of 20V and a load of 300mA at 150°C ambient temperature, the EVM does not exhibit thermal shutdown until the case temperature reaches 154°C ambient temperature with no forced air cooling.
