How can a transistor be used as a voltage regulator?

The transistor works as a variable resistor regulating its collector emitter voltage in order to maintain the output voltage constant. The figure below shows the transistor series voltage regulator. With the input operating conditions, the current through the base of the transistor changes.

How do you step down DCV 12V to 5V?

Connect 12 v to pin 1 ,pin 2 is the ground and pin3 gives 5v. Don’t want to use IC or not getting it,use a voltage divider using 2 resistors and you are done with it. Connect 12 v across the series combination of 4.7k ohm and 6.8k ohm(readily available standard ) resistor and take the output across 4.7k ohm.

Do voltage regulators need capacitors?

Most voltage regulators (especially LDO types) require a capacitor on the output for stability, and it will usually improve transient response even for regulators like the 7800 that may not strictly require it. An input capacitor is usually required to reduce source impedance.

What is regulator circuit?

A voltage regulator is a circuit that creates and maintains a fixed output voltage, irrespective of changes to the input voltage or load conditions. Voltage regulators (VRs) keep the voltages from a power supply within a range that is compatible with the other electrical components.

How does an AC voltage controller work?

A voltage controller, also called an AC voltage controller or AC regulator is an electronic module based on either thyristors, triodes for alternating current, silicon-controlled rectifiers or insulated-gate bipolar transistors, which converts a fixed voltage, fixed frequency alternating current (AC) electrical input

What is AC voltage regulator?

The ac voltage regulator is a static circuit that accepts a variable ac voltage input and produces a regulated ac voltage output. The output voltage is maintained for changes in input voltage, output load current, and load power factor.

How current boosting is achieved in a 723 IC?

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.

What is a voltage regulator?

voltage regulator, any electrical or electronic device that maintains the voltage of a power source within acceptable limits. The voltage regulator is needed to keep voltages within the prescribed range that can be tolerated by the electrical equipment using that voltage.

What High current means?

High current refers to lots of electrons moving through a cross section of conductor per second. That can happen at lower voltages when there is little resistance. High voltage refers to lots of energy per electron pushing on the electrons.

Why BJT is voltage regulator?

When a voltage regulator is made, it comprises of zener diode which is the main regulating element but the required amount of current may not be able to pass through it so as we know that bjt is a current controlled device it can be used to amplify the current to the required level.

What are the different types of IC voltage regulators?

There are three types of IC voltage regulators: IC linear voltage regulators, IC switching voltage regulators, and DC/DC converter chips. IC linear voltage regulators use an active pass element to reduce the input voltage to a regulated output voltage.
