Abstract:
A low drop-out (LDO)/load switch linear voltage regulator (LVR) circuit having a first input terminal and a first output terminal, includes: a passive network with a second input terminal connected to the first input terminal and a second output terminal; a feedback network with a third input terminal connected to the first output terminal and a third output terminal; a pass element having a fourth input terminal connected to the first input terminal, a fourth output terminal connected to the first output terminal and first control terminal; a combiner having a fifth input connected to the second input, a sixth input connected to the third output and a fifth output connected to the first control terminal.
