ELECTRONIC CIRCUIT SUPPLY VOLTAGE STABILIZER Russian patent published in 2020 - IPC G05F3/16 

FIELD: radio electronics.

SUBSTANCE: invention relates to radio electronics and can be used as a supply voltage stabilizer when designing micro power electronic circuits with self-contained power supply. In electronic supply voltage supply stabilizer, comprising control bipolar transistor in form of emitter follower, which collector is connected to potential output of unstable voltage source, field transistor with p-n-junction and channel conductivity identical to bipolar transistor, drain of which is connected to collector of control transistor, potentiometer in form of two series-connected resistors, wherein free terminal of first resistor is connected to base of control transistor, and load connected between emitter of bipolar transistor and common source bus, source of field transistor is connected to connection point of bipolar transistor base and first resistor, gate of field transistor is connected to connection point of first and second resistors, and free terminal of second resistor is connected to common bus through two series-connected in forward direction of semiconductor diodes.

EFFECT: device simplification at higher efficiency.
