Voltage stabilizing circuit

Abstract

The invention discloses a voltage stabilizing circuit. The voltage stabilizing circuit comprises an USB_MINI joint, a switch (S), a power supply (VCC) (Volt Current Condenser), an electrolytic capacitor (C1), a capacitor (C2), a voltage stabilizing chip AMS (Advanced Monolithic System) 117, an electrolytic capacitor (C3), a capacitor (C4), a resistor (R1) and a light emitting diode (VD); a 1st pin of the S is connected with 5V, and while a 2nd pin of the S is connected with the VCC, a positive pole of the C1, one end of the C2, and the 1st pin of the voltage stabilizing chip AMS117; the negative pole of the C1 is connected with the other end of the C2, a 3rd pin of the voltage stabilizing chip AMS117, the negative pole of the C3 and the negative pole of VD and then grounded; the 2nd pin of the voltage stabilizing chip AMS117 is connected with the positive pole of the C3, the VCC, one end of the C4 and one end of the R1. The voltage stabilizing circuit has the beneficial effects that the principle is simple and easily understood, and thus the convenience is provided for people to use.

[0002] In the era when electronic technology is updated and constantly changing, and computer programming languages ​​are widely used, it is essential to learn circuits. With the development of society, the development of the electronic industry is very rapid, and people's demand for electronic products is also increasing. There are more and more requirements for the functions of electronic products. Any electronic product is inseparable from the circuit. The circuit is like the brain of the electronic product. It plays a very important role, and the design of the power supply is particularly important in the design of the circuit. Without a suitable power supply circuit, it cannot run, so the circuit must have a suitable voltage to drive, so it is also particularly important for the design of the voltage regulator circuit. Suitable The voltage will make the circuit run normally. The design of the existing voltage regulator circuit is complicated and the principle is relatively difficult. Therefore, the design of the voltage regulator circuit still needs to be studied.
