Using a 5v input with a 500mah draw which resistir wattage should I be looking for? The input will be 3-40 volts and will output 5 volts and sometimes 3.3v would a 1/4 watt resistor handle this on the converter? I am powering my project through a vehicle batteey terminal. I plan on using the LTM8021 …

proper wattage for a resistor?
