This specific regulator will convert anything between 4.75VDC and 15VDC to a regulated 3.3VDC. These do not technically require any additional circuitry to work; when 4.75V – 15V is applied to the input pin the output pin will have 3.3V out. We do recommend using a few capacitors with these to ensure stability.

Please note: As the load increases towards the maximum rating on these regulators they do tend to get quite warm. The temperature increase is also proportional to the input voltage; the higher the input voltage the warmer this regulator will run. Basically, the higher the input voltage, the lower the sustainable output current will be. Heatsinks are always a good idea with these chips!
