Frequently asked questions
What input voltage do I need?
The input must stay above 5 V by the dropout voltage listed in the datasheet, which is about 1.5 V at full load for this family. Using an input of roughly 7 V to 9 V is a common practice to keep the regulator in regulation.
How do I handle heat at high current?
Power dissipated in the regulator equals (input voltage minus 5 V) multiplied by the load current. At high current, use a heatsink or a large copper area on the PCB as recommended in the datasheet.
