IC Regulator | Fundamentals of Electronic Circuits Lesson

An Integrated Circuit (IC) regulator is a compact, monolithic voltage regulator that provides a stable and regulated output voltage. IC regulators are widely used in electronic systems due to their ease of implementation, low component count, and stable performance. There are two main types of IC regulators: linear IC regulators and switching IC regulators.

  1. Linear IC Regulators: Linear IC regulators are based on the linear voltage regulation principle, where a series-pass transistor is used to control the voltage drop between the input and output. Some common linear IC regulators include:

a. Fixed Voltage Regulators: These regulators provide a fixed output voltage, such as the popular 78xx series (positive voltage) and 79xx series (negative voltage), where ‘xx’ represents the output voltage (e.g., 7805 for +5V, 7812 for +12V, 7912 for -12V).

b. Adjustable Voltage Regulators: These regulators allow the user to set the desired output voltage using external resistors. The LM317 (positive voltage) and LM337 (negative voltage) are common examples of adjustable voltage regulators.

Linear IC regulators are simple to use, have low output noise, and offer a fast transient response. However, their efficiency is relatively low, particularly when the difference between input and output voltage is significant.

  1. Switching IC Regulators: Switching IC regulators use switching principles to achieve voltage regulation. They control the output voltage by rapidly switching the input voltage on and off and adjusting the duty cycle of the switching waveform. Switching IC regulators can be further classified into different types, such as:

a. Buck (Step-Down) Regulators: These regulators convert a higher input voltage to a lower output voltage by reducing the duty cycle of the switching waveform.

b. Boost (Step-Up) Regulators: These regulators convert a lower input voltage to a higher output voltage by increasing the duty cycle of the switching waveform.

c. Buck-Boost Regulators: These regulators can either step up or step down the input voltage, depending on the desired output voltage and input voltage levels.

Switching IC regulators have higher efficiency compared to linear IC regulators, especially for large input-output voltage differences. However, they produce more output noise and have a slower transient response.

In summary, IC regulators are integrated voltage regulators that provide stable and regulated output voltage for electronic systems. They are available as linear or switching regulators, each with their advantages and disadvantages. The choice between linear and switching IC regulators depends on factors such as efficiency, output noise, transient response, and input-output voltage difference.

  1. I do not know whether it’s just me or if perhaps everybody else encountering issues with your blog. It appears like some of the text within your posts are running off the screen. Can somebody else please provide feedback and let me know if this is happening to them as well? This could be a issue with my internet browser because I’ve had this happen previously. Thank you

  2. I’ve been browsing online greater than 3 hours today,
    yet I by no means found any interesting article like yours.
    It is lovely worth enough for me. In my view, if all webmasters and bloggers made
    excellent content material as you did, the net will likely be
    much more useful than ever before.

  5. I simply could not go away your web site prior to
    suggesting that I actually enjoyed the standard information an individual provide to your visitors?

    Is going to be again regularly to check
    up on new posts

    to suggest you few interesting things or tips. Maybe you could write next articles referring to this article.
    I wish to read even more things about it!

  7. When I initially commented I clicked the “Notify me when new comments are added” checkbox and now
    each time a comment is added I get four emails with the same comment.
    Is there any way you can remove people from that service?
    Appreciate it!

  8. Greetings from Los angeles! I’m bored at work so I decided to check out your website on my iphone during
    lunch break. I enjoy the information you present here and can’t wait to take a look
    when I get home. I’m shocked at how quick your blog loaded on my phone
    .. I’m not even using WIFI, just 3G .. Anyways, excellent
    site!

  9. It’s my belief that mesothelioma is actually the most lethal cancer. It’s got unusual properties. The more I really look at it the more I am confident it does not respond like a true solid flesh cancer. When mesothelioma is usually a rogue virus-like infection, so there is the potential for developing a vaccine as well as offering vaccination to asbestos open people who are vulnerable to high risk associated with developing potential asbestos relevant malignancies. Thanks for discussing your ideas on this important ailment.

  24. Ask that they e-mail or name you straight in order that you can also make it right.
    Do not be afrid to proceed your quest with other clinics until you discover
    the onne that is best for you. An efficient remedy provided by a therapeutic massage therapist miht do better than yyou may think about and inn addition the very best thing
    about the sort of treatment is the fact that it may eradicate stress, nervousness,
    and depression which are making your life extraordinarily hard and an excruciating one.
    They assist to bring a greater steadiness in mmy life and provide any
    time for relaxation. People will ssee your response and feel better
    about utilizing your therapeutic massage providers.
    Stress is just the response our bodiess have from all of
    the demands positioned on it. While people dwell longerr as we speak, they usually experience chronically high rnges of
    stress and depression. Be sure it’s a small window of
    time to seize consideration and inspire individuals
    to e-book. Custom audiences are for locating individuals who have already come into contact along with your model,
    or “look like” those who’ve. Forr instance,
    you might begin by seeing a industrial (consciousness), then cazll the enterprise or fill outt a contact kind (motion) or guide an appointment (conversion).
