DC VOLTAGE STABILIZER Russian patent published in 2017 - IPC G05F1/56 G05F1/573 

FIELD: electrical engineering.

SUBSTANCE: invention relates to stabilized secondary power supply sources and can be used to supply different wireless devices with power. In a DC voltage stabilizer connected to a source of input DC voltage, comprising a control transistor, a LDC-filter, an additional power supply source, a Schmitt trigger, a driver, a reference voltage source, a differential amplifier and an output voltage divider, according to the invention there is an additional transistor to lock the control signal output to the control transistor, that provides its protection against high levels of currents observed at a short circuit of outputs or at the initial moment of time.

EFFECT: higher reliability by introducing a circuit of protection from short-circuits of outputs or at the moment of connecting an input voltage source; higher quality of stabilization by applying a thermally stable reference voltage source; reduced power loss by reduction of the driver output current and wider range of input voltages using voltage addition in the control circuit between the gate and the drain of the control MIS-transistor.
