DC voltage stabilising circuit - has regulating transistor controlled by voltage of voltage divider across stabiliser output via transistor arrangement

摘要

DC voltage stabilizer has regulating transistor controlled by voltage of voltage divider across stabilizer output via transistor arrangement. The switching section of an additional transistor (20) is connected in series to the switching section of a transistor (19) of the transistor arrangement (14, 15, 19). Voltage on the intersection between two transistors (19, 20) is provided to control the regulating transistor (11). At either side of the intersection, resistors (18, 21) are connected in the circuit of the two in series connected transistors (19, 20). The base of the regulating transistor (11) is connected to the collector-emitter section of a n-p-n transistor (14) via the series connection of a resistor (13).
