Frequently asked questions
Does this regulator need a heat sink?
The regulator dissipates the difference between input and output voltage as heat, so a higher input voltage and higher load current increase heating. Check the datasheet thermal figures and add a heat sink or copper area if the device runs hot.
What is the maximum current this regulator can supply?
The listing gives a maximum output current of 0.5 A, with thermal shutdown and short-circuit protection included. Do not load the output beyond this rating.
