Improved regulation of direct current voltage from an unstable voltage source through a transitor series regulator to a load is provided by a lockout circuit that prevents current flow through the series regulator when the source voltage is removed from the lockout circuit, by a current limiter circuit that controls the series regulator as a function of current supplied to a load, and by a current cutoff circuit that prevents current flow through the series regulator when the output voltage falls below a selected magnitude.
