Zusammenfassung:	A low drop-out (LDO) regulator, includes an NMOS transistor having one of a source and drain terminal configured to be coupled to a voltage supply and the other of the source and drain terminal coupled to the low drop out voltage regulator output. A gate driver for the LDO regulator includes a boost converter having a boost converter input configured to be coupled to a boost converter reference voltage, a boost converter output configured to output a boosted voltage greater than the boost converter reference voltage and the voltage supply; and a boost converter clock input configured to receive a clock signal. The gate driver further includes a notch filter having a notch filter input coupled to the boost converter output and a notch filter output coupled to the gate driver output.
