Abstract
An electronic device includes a low drop-out regulator for providing a regulated output voltage. The low drop-out regulator generally comprises a power MOSFET transistor having a gate coupled to a driver. The driver has a first path including an NMOS transistor and being coupled to the gate of the power MOSFET, a second path having a PMOS transistor and being coupled to the gate of the power MOSFET, and a switch for alternately switching between the first and second paths so as to provide a voltage to the gate of the power MOSFET ranging from ground to a power supply level.
