Voltage stabilizer on OU
In drawing is given by font face the circuit of a voltage stabilizer which can be used for a food of the equipment collected on operational amplifiers of the K140 series. Feature of the stabilizer is that its OU included in a chain of feedback, eats not from a separate source, and neosredstvenno from a stabilizer exit. The factor of stabilization of the device - about 1000, target resistance does not exceed 0,01 Ohm, efficiency - 45 %. Rated current of load not less than 0,2 A.Pulsatsiya of target tension (double amplitude) - no more than 60 мкВ. The stabilizer is efficient in a range of temperatures from-20 to +60 about Page. Temperature drift of target tension less than 0,05 %. Target tension can be increased to 27 In to plus (minus) of 10 %. In this case between a conclusion of the 7th chip and an exit +25,2 In it is necessary to turn on the resistor resistance about 200 Ohm. The cascade on the T1 transistor serves as dynamic loading of the T4 transistor is essentially increases the general factor of strengthening of UPT. the P702A Transistor can replace p with on П702, КТ805. It is possible to replace KT603G transistors on П308, П309, and КТ201В and КТ203В - on МП103 or МП106.
