These are generally considered as fixed voltage regulators but their functions can be manipulated to convert them into variable voltage regulators. The important parameters of 78 XX series are.

Cheap chinese regulators are extremely unreliable. There are constructed using inefficient thyristor circuits prone to overheat and fail after short time, particularly with light loads (worst case ...

Voltage regulator IC’s, with 3 pins, from LM7805 and LM7812 series are excellent for usage in voltage regulator circuits. If you need higher currents, up to 3 A, you must add a complementary ...

A VRM is an essential part of every computer, but even many computer-savvy enthusiasts don't know what it is or how it works.

Explore the concept of negative feedback and its role in maintaining system stability across various applications.

QUESTION: There are so many different voltage regulators on the market these days. How do I pick one that will be good for my circuit? ANSWER: Wow, this is a tough question, but also a good one. I ...

Build miniature IoT devices using this compact, cost-effective GPS and GSM module. Fully open-source with design files and ...

IC2 LM317T 1.5amps, TO-220 ($0.64) – At 1.5amps, this regulator supplies enough power for most digital circuits. We prefer the surface-mount D2Pack version (IC4) because we don’t like to drill ...

Three-terminal voltage regulators physically look like a power transistor and act as an automatic variable resistor to bring a supply voltage down to a desired voltage for circuits they power.
