In some special applications, required supply voltage, which is very accurate, and It looks like, how popular each one. Then, to improve the output voltage of voltage regulator better. With “improve” the Commonwealth, (that is to increase the electrical potential, it gives rise).But this, have in vain like that in short-circuit common, often looks into [...]
This circuit designs for modify power supply input 12V from battery or the other. Have the level voltage be down be left 9V be stable or , 9V at 2 Amp DC power supply . By this circuit gives usual equipment , seek easy. Be integrated circuit IC 741 and power transistor 2N3055. Besides this [...]
A low-drift voltage reference can be easily made by converting a zero temperature coefficient current to a voltage. JFETs biased slightly below pinch-off exhibit a zero temperature coefficient drain current (ID) as shown in Figure 1. With the above property and a micropower operational amplifier, used to convert the drain current to a voltage, a [...]
