Abstract
A low drop-out (LDO) regulator includes a voltage-to-time converter (VTC) responsive to a reference voltage and an output voltage. The VTC generates a voltage pulse signal having: (i) a sign associated with a magnitude of the output voltage relative to a magnitude of the reference voltage, and (ii) a first pulse width proportional to a difference the output voltage and the reference voltage. A driving time-to-current converter (TIC) drives a gate node with a non-zero driving current proportional to the first pulse width of the voltage pulse signal. A slew adjusting circuit drives the gate node with a non-zero slew adjusting current, in response to the first pulse width of the voltage pulse signal being equal to or greater than reference time interval. A compensation TIC drives the output node with a non-zero compensation current having a magnitude proportional to the first pulse width of the voltage pulse signal.
