Regulator to improve better

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 the reverse bias, making it less protection, the result is a circuit can be damaged easily.
For this circuit, it is a problem that has one.By placing a diode German Niam D1, to protect the Commonwealth to prevent the reverse bias exceeds 0.2 volt when the short-circuit. , that is, not to prevent regulator damage.
In addition, adding a capacitor C2 to, it also ensures that the circuit will have a better image stability. The diodes D1 and D2 (for example) increases the output voltage to rise about 1.3 volts.

12V to 9V 2A step down dc converter using IC 741 and 2N3055

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 circuit still can fine to differ out voltage with well and have picture stability although load modify. The zener diode 8.2V be formed fix stable reference or voltage the referable at pin3 of the integrated circuit and the VR1 for give fine the level volt output.

Basic DC voltage Regulated 13V low current.

Today I searches the circuit in old book. Meet power supply circuit. very plentiful may advantage with friends. Then bring see this circuit basically the base of DC voltage Regulator follow the circuit gives voltage , get +13V and -13V by it uses Zener Diode . Perform maintain one’s position voltage. Be stable and use the principle of divide Voltage. With electronic resister makes the wage has pushed the electricity that is equal both of the positive and negative. The detail is other, request a friend sees in the circuit next.
