Title: Low stand-by low-loss constant-voltage electric power supply
Inventor: SATOU YUUJI
IPC: G05F1/56
Filed: 1980-03-06
Abstract: PURPOSE: To obtain a constant-voltage output of low voltage which is small in not only stand-by current but also loss voltage, by using the diode connection of the transistor, and also compensating the temperature characteristic by the temperature characteristic of the field effect transistor.  
     CONSTITUTION: When the input voltage V i  becomes high, the voltage of noninverted input + of the error amplifier DA becomes higher than the voltage of inverted input -, a drive current Ib of the transistor Tr2 decreases, a load current Ie decreases, and the output voltage V o  is kept constant. Also, even in case when the load current I e  is varied by a variation of the load L, the output voltage V o  is kept constant in the same way. In case when temperature has been varied, a current of the field effect transistor FET is made small, it is operated in the area where the temperature coefficient is positive, the negative temperature coefficient of the transistor Tr1 is negated by the positive temperature coefficient of the field effect transistor FET, and the output voltage having no variation is obtained. Also, since the transistor Tr2 is driven by the output of the error amplifier DA, the stand-by current at the time of no-load is very small.
