MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202541038572 A) filed by Samsung Electronics Co. , Ltd. on April 22, 2025, for Device For Optimizing Noise At An Output Of High Voltage Low-Dropout Regulator.
Inventors include Zahir, Zaira; and Devendran, Deepa.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: A device comprises a first intermediate LDO regulator configured to generate a first enhanced reference voltage, a resistor-capacitor (RC) circuit connected to the first intermediate LDO regulator, the RC circuit comprising an RC filter configured to generate a filtered reference voltage based on the first enhanced reference voltage; a second intermediate LDO regulator connected in parallel to the first intermediate LDO regulator and the RC circuit; the second intermediate LDO regulator generates a second replica enhanced reference voltage based on the input reference voltage; a low noise buffer selectively receiving one of the filtered reference voltage or the second replica enhanced reference voltage to generate a buffer reference voltage. These are configured to be transmitted to the high voltage LDO regulator based on an operational state of the RC filter. The high voltage LDO regulator is configured to generate the output based on the buffered reference voltage.
