Abstract
A low drop-out voltage regulator (LDO) circuit structure includes a drive transistor with first connected to an input voltage node, a second terminal connected to an output voltage node and a voltage divider, and a third terminal (i.e., a control terminal). The structure employs a pair of concurrently operating feedback control loops between a feedback voltage node of the voltage divider and the control terminal to continuously adjust a control voltage applied to the control terminal and thereby reduce ripple of an output voltage (Vout) at the output voltage node. A first feedback control loop includes comparator and a push capacitor connected between the feedback voltage node and the control terminal. The second feedback control loop includes an operational amplifier connected between the feedback voltage node and the control terminal. The first feedback control loop operates a faster speed than the second to quickly initiate the necessary control voltage adjustments.
