Title: Low drop-out voltage regulator and power management integrated circuit including the same
Inventor: GWON HUI DONG
IPC: G05F1/575
Filed: 2021-03-18
Abstract: A low voltage dropout regulator includes a voltage-time converter, a driving time-current converter, a slew control circuit, a pass transistor, and a compensation time-current converter. The voltage-time converter receives a reference voltage and an output voltage provided from an output node, and generates a voltage pulse signal having a sign related to a relative magnitude of the output voltage with respect to the reference voltage and a pulse width proportional to a difference between the reference voltage and the output voltage. When the sign indicates that the relative magnitude is not zero based on the voltage pulse signal, the driving time-current converter charges or discharges a gate node with a driving current corresponding to the pulse width of the voltage pulse signal. The slew control circuit is activated when the pulse width of the voltage pulse signal is greater than or equal to a reference time interval, and charges or discharges the gate node with a slew control current based on the voltage pulse signal. The pass transistor is connected to the gate node, and regulates an input voltage based on the driving current and selectively based on the slew control current to provide the output voltage to the output node. The compensation time-current converter charges or discharges the output node with a compensation current corresponding to the pulse width of the voltage pulse signal based on the voltage pulse signal. The low voltage dropout regulator has improved performance.
