Title:
LINEAR POWER SOURCE
Document Type and Number:
WIPO Patent Application WO/2020/116208
Kind Code:
A1
Abstract:
A linear power source 1 comprises: an output transistor 10 that is connected between an input end of an input voltage VIN and an output end of an output voltage VOUT; a driver 30 for driving the output transistor 10 so that a feedback voltage VFB according to the output voltage VOUT matches a reference voltage VREF; a current detection unit 50 for detecting an output current IOUT flowing to the output transistor 10; and a voltage adjustment unit 40 for adjusting the reference voltage VREF or the feedback voltage VFB so that a differential voltage between a first voltage (for example, VIN itself) according to the input voltage VIN and a second voltage (for example, VOUT itself) according to the output voltage VOUT or the reference voltage VREF will not fall below an offset voltage Voffset according to the output current IOUT.
