Power supply apparatus and a test system including the same
A power supply apparatus includes first through M-th switching regulators, first through N-th multiplexers, and first through N-th linear regulators, where each of M and N is a natural number greater than or equal to two. The first through M-th switching regulators generate first through M-th reference power signals using an input power signal. The first through N-th multiplexers select one of the first through M-th reference power signals, in response to a power selection signal, to provide first through N-th selection power signals. The first through N-th linear regulators generate first through N-th output power signals using the first through N-th selection power signals. The first through N-th linear regulators are connected to the first through N-th multiplexers, respectively.
