Latest Patents

Seongwon Joo holds a patent for a "Low drop-out regulator and power management integrated circuit including the same." This invention features an LDO regulator that comprises an error amplifier, a power transistor, a monitoring circuit, and an adaptive pole adjusting circuit (APAC). The error amplifier is designed to compare a reference voltage with a feedback voltage, generating a first error voltage based on this comparison. The power transistor, which has a gate coupled to the output terminal of the buffer, regulates the input voltage based on a second error voltage derived from the first error voltage, thereby providing an output voltage to an output node. The monitoring circuit, connected in parallel with the power transistor, generates a control voltage associated with the load current. The APAC selectively connects an adjusting capacitor between the output terminal of the error amplifier and the ground voltage in response to the control voltage.
