Hello,
Some linear voltage regulators do not work if the output voltage drops below 0V (-0.5V for example) before input voltage is applied. The problem can be solved by placing a schottky diode from the output to ground in order to prevent the output voltage from falling much below the 0V.
Does anyone know the reason for this behaviour of linear voltage regulators? Thanks.
