Serial regulating circuit with adjustable output voltage

Published:2011/4/13 2:46:00 Author:Nicole | Keyword: serial regulating, output voltage | From:SeekIC

The output voltage of this circuit can adjust from 0 to the maximum continuously. The datum quantity is the constant current circuit which is charged by auxiliary power supply. The reference current can be adjusted by 500Ω trimming resistor, the value is about 7mA. The current flows 2.5kΩ potentiometer and forms a voltage drop, its value is from 0 to maximum output, then the output voltage UA can be adjusted between 0 and the maximum.
