VOLTAGE STABILIZER Russian patent published in 2007 - IPC G05F1/569 

FIELD: electrical engineering, possibly sources for secondary power supply of radio-electronic apparatuses.

SUBSTANCE: stabilizer includes regulating transistor 1 whose emitter is connected with inlet terminal and collector with outlet terminal; transistor 2 of opposite conductivity type. Collector of transistor 2 is connected with base of transistor 1, its base is connected with outlet of output voltage divider 4,5, its emitter is connected through Zener diode 3 with outlet terminal and through electric current setting resistors 12 - with common bus. According to invention starting capacitor 7 is connected between base of transistor 2 of amplifier and base of transistor 1 whose base-emitter junction is by-passed by diode 11 in reverse direction.

EFFECT: improved operational reliability of stabilizer.
