Faster responding regulators (or converters) do provide a way to reduce the total amount of capacitance by shifting more of the energy load from the regulator's output capacitors to the input ...

What is the function of a voltage regulator IC? A voltage regulator generates a fixed output voltage of a preset magnitude that remains constant regardless of changes to its input voltage or load ...

A critical aspect of power supplies is dc supply-voltage stability.

A recent Design Idea, “ Three discretes suffice to interface PWM to switching regulators, ” demonstrated one way to use PWM to control the output of a typical switching voltage regulator. There were ...

Adding a secondary feedback circuit can help resolve voltage-headroom and adjustment-resolution limitations when replacing an analog potentiometer with a digipot.

The regulator has internal protection, a boost MOSFET, current sensing, and compensation, which simplifies its design and minimizes components and PCB size.

Every project needs a power supply. As 3.3volt logic replaces 5volt systems, we’re reaching for the LM317 adjustable voltage regulator, rather than the classic 7805. We’ve found four different ...

PID controller design has long been central to the stable and efficient operation of automatic voltage regulator (AVR) systems worldwide. Contemporary research in this field focuses on the ...

In the design of power supplies, the desired output voltages can be set manually. This is accomplished in most integrated power supply circuits, as well as switching and linear regulator ICs, with the ...

In his video [Afroman] describes how the LM317 can be used to regulate current rather than voltage to provide a constant current source under varying load.
