LM117 Protection Diodes The LM117 datasheet states the following "When an output capacitor is connected to a regulator and the input is shorted, the output capacitor will discharge into the output of the regulator. The discharge current depends on the value of the capacitor, the output voltage of the regulator, and the rate of decrease of VIN. In the LM117, this discharge path is through a large junction that is able to sustain 15A surge with no problem. This is not true of other types of positive regulators. For output capacitors of 25 μF or less, there is no need to use diodes." Does this apply to all types of capacitors including those with virtually no ESR, such as ceramics, or does it only apply to types of capacitors with an appreciable amount of ESR such as tantalums?
