10 Power Supply Recommendations

The input supply to the LM117QML-SP must be kept at a voltage level such that its maximum input to output differential voltage is not exceeded. The minimum dropout voltage must also be met with extra headroom when possible to keep the LM117QML-SP in regulation. An input capacitor is recommended, especially when the input pin is located more than 6 in away from the power supply source.
