How to hook up a voltage regulator?

Before we can hook up the circuit, lets first go over the pinout diagram of the voltage regulator, which is vital for hooking up the circuit. A voltage regulator is a 3-terminal device. Pin 1 is the Input Pin. The output voltage of whatever voltage source you want to regulate down (whether its a transformer, battery, etc.) is fed into this pin.

What do the parts numbers on a voltage regulator mean?

Enough talk, now for the actual part numbers. The most common series of voltage regulators is the 78XX series. The two digits after the 78 represent the output voltage of the regulator, for example the 7805 is a 5V regulator and the 7812 is a 12V regulator.

What is the purpose of a voltage regulator?

The purpose of a voltage regulator is to provide a constant output voltage regardless of the load resistance. In other words, an ideal regulator would produce a voltage that is (for example) exactly 3.3 V when connected to a 100 kΩ load and exactly 3.3 V when connected to a 5 Ω load.

What are the pins on a voltage regulator?

Look from the front, the first pin (on the left) is the Adjustable Pin, the middle is Vout, and the last pin (on the right) is Vin. Now that you know the pins, lets see how the circuit is set up: Here you see we connect two resistors to the voltage regulator. These resistors determine the voltage that the voltage regulator adjusts to and outputs.

How do you wire a voltage regulator?

How do you wire a voltage regulator to an alternator? Open the hood of your car. Remove the black battery cable from the car’s battery terminal using a wrench. Locate the voltage regulator. Find the multi-wired harness nearby the alternator and voltage regulator. Insert the plug into the socket on the voltage regulator.

How to choose a voltage regulator?

Voltage Regulator Selection Guide. Consider these factors when selecting a voltage regulator: 1. Input Voltage and Output Voltage. Ideally, you know the input voltage range and the required output voltage that you will be working with. Each voltage regulator chip is designed to be used for a specific output voltage.
