MUMBAI, India, Aug. 22 -- Intellectual Property India has published a patent application (202517040822 A) filed by Vanchip (TIANJIN) Technology Co. Ltd., Tianjin, China, on April 28, for 'ldo circuit having current limiting function, and chip and electronic device.'
Inventor(s) include Gao, Chenyang; and Lin, Sheng.
The application for the patent was published on Aug. 22, under issue no. 34/2025.
According to the abstract released by the Intellectual Property India: "Provided are an LDO circuit having a current limiting function, and a chip and an electronic device. The LDO circuit comprises a bandgap reference circuit (101), an error amplifier (102), a power transistor (103), a feedback resistor network (104), and a current limiting function module (105), wherein the current limiting function module (105) comprises a load current mirror unit (107), a reference current unit (108), a current comparison unit (109), a hysteresis shaping unit (110), and a control current output unit (111). The current limiting function module (105) controls the on or off of a negative feedback loop and a current limiting output unit in the LDO circuit by comparing a load current with a reference current, so as to control an output current, thereby providing a stable direct current bias voltage for a radio frequency chip under working conditions such as large power and a complex application environment."
The patent application was internationally filed on Feb. 04, 2024, under International application No.PCT/CN2024/075711.
