Abstract:
A regulator circuit that makes it possible to supply a voltage which enables a load circuit to operate normally, even if an external power supply voltage is momentarily interrupted or dropped, includes a ZD/R parallel circuit (a backflow prevention diode and in parallel with a resistor) that is connected between an external power supply voltage terminal and the drain of a MOSFET.
