ABSTRACT:
An apparatus for supplying a glitch-free, regulated voltage at a voltage output includes a main transistor, which is connected between an intermediate potential and the voltage output, a bypass transistor, which is connected between a supply potential and the voltage output, the intermediate potential being lower than the supply potential and the intermediate potential and the supply potential being derived from a common voltage source, a regulation circuit for applying a main control potential to the main transistor, in order to regulate a voltage at the voltage output to a desired voltage, and a control circuit for generating a bypass control potential as a function of the supply potential and the main control potential, and to apply the bypass control potential to the bypass transistor.
