<p>A low-drop voltage regulator (20) comprising a P type power transistor (6) having an input terminal (2) connected to a supply source (3), an output terminal (4) connected to a load (5), and a control terminal driven by the output of an operational amplifier (21) having its non-inverting input (+) connected to a reference voltage source (13), and its inverting input (-) connected to the output terminal (4) of the power transistor (6). To improve the regulation characteristics of the regulator (20) without jeopardizing stability, even under normally critical conditions, provision is made for a feedback network (24) including a capacitive component (26) between the output and inverting input (-) of the operational amplifier (21). <IMAGE></p> |
