What is the working principle of regulator?
The main principle behind the working of such a regulator is that a large proportion of the change in supply or input voltage appears across the transistor and thus the utput voltage tends to remain constant.
How do you test a IC regulator?
We take the probes of the multimeter and place the positive probe (normally the red probe) on the input pin of the voltage regulator and the negative probe (normally black probe) on the ground pin. The voltage that we should read should be higher than the voltage the regulator is rated to output.
How an IC 723 is worked as regulator?
It consists of a voltage reference source (Pin 6), an error amplifier with its inverting input on pin 4 and non-inverting input on pin 5, a series pass transistor (pins 10 and 11), and a current limiting transistor on pins 2 and 3. …
What is the use of regulator IC in power supply?
The chief purpose of most power-supply ICs is to regulate. These devices take an unregulated input voltage and provide a regulated output voltage. Restated most simply, these ICs provide an output voltage that remains steady despite varying input voltage or output current.
What are the 2 types of regulators?
Two types of regulators are used: step regulators, in which switches regulate the current supply, and induction regulators, in which an induction motor supplies a secondary, continually adjusted voltage to even out current variations in the feeder line.

How do I test an IC with a multimeter?
Take the terminal-cable from multimeter and connect it one by one to each of the pins of another side separately. If the beep sound occurs of there is a continuity in more than 50\% of the combinations then there is a good chance of the IC to be shorted from inside.
How do I know if my IC is good or bad?
It mainly measures the DC working voltage value of each pin to the ground; Then compared with the nominal value, the quality of integrated circuit can be judged. It is one of the most commonly used methods to judge whether an integrated circuit is good or bad by using the voltage measurement method.
What is IC 723 voltage regulator?
The 723 voltage regulator is commonly used for series voltage regulator applications. It can be used as both positive and negative voltage regulator. It has an ability to provide up to 150 mA of current to the load, but this can be increased more than 10A by using power transistors.
Which type of voltage regulator is IC 723 *?
op-amp voltage regulator
IC 723 is used as an op-amp voltage regulator.
What is voltage regulation using IC?
A voltage regulator is an integrated circuit (IC) that provides a constant fixed output voltage regardless of a change in the load or input voltage. It can do this many ways depending on the topology of the circuit within, but for the purpose of keeping this project basic, we will mainly focus on the linear regulator.
What is the function of an IC voltage regulator?
It is an integrated circuit whose basic purpose is to regulate the unregulated input voltage (definitely over a predefined range) and provide with a constant, regulated output voltage. An IC based voltage regulator can be classified in different ways.
What is the function of a switching regulator?
A switching regulator converts the dc input voltage to a switched voltage applied to a power MOSFET or BJT switch. The filtered power switch output voltage is fed back to a circuit that controls the power switch on and off times so that the output voltage remains constant regardless of input voltage or load current changes.
How does a linear regulator work in a circuit?
How Linear regulators work Linear regulators uses a closed feedback loop to bias a pass element to maintain a constant voltage across its output terminals. In figure 1, the op-amp drives the base of Q1 to ensure that the voltage at its inverting input will be equal to the voltage reference at its non-inverting input.
What is a fixed output voltage regulator?
A voltage regulator generates a fixed output voltage of a preset magnitude that remains constant regardless of changes to its input voltage or load conditions.
