Linear regulator doesn't always operate correctly depending on order in which power pins are connected

Try connecting a reverse-biased Schottky diode such as 1N5819 across each regulator output.

Can somebody explain to me how this circuit actually works? (Linear voltage regulator and PNP transistor as current boost)

It may be easier to understand this circuit by first considering it without the transistor. In that scenario, all the current to the output must flow through the 68R resistor and the LM2931. If a ...

Can somebody explain to me how this circuit actually works? (Linear voltage regulator and PNP transistor as current boost)

The voltage across R is also the voltage between the base and emitter of the transistor. If the output current is small enough, all of the output current passes through R and the transistor is off. ...
