This article presents linear regulators and the computation of its efficiency. It also describes the advantages and other properties of a linear regulator, as well as the low drop out (LDO) regulator, ...

Many low-dropout voltage regulators include an enable-input pin that can also serve as an inexpensive alternative to a voltage-supervisor IC. Although the enable pin normally serves as a means of ...

Is it possible to design an unconditionally stable linear voltage regulator? In fact, many believe that most regulator ICs are unconditionally stable. The answer is both simple and complex, if it is ...

The importance of low Iq with linear regulators and LDOs. A look at low-Iq voltage supervisors in portable electronics. Battery-voltage supervisors in the IoT. In my article “What is the Essence of ...

Electronic systems often require multiple voltages to power the various internal circuits. Non-isolated regulators are a common and easy way to convert one voltage to another. Regulators typically ...

Linear Technology has produced a high-power dual voltage reference, allowing the reference replace the circuit power supply regulator. Specs are excellent, with outputs offering 0.05% initial accuracy ...

Infineon has introduced six automotive linear regulators, protected against 40 or 45V, and supplying 3.3 or 5V at up 500mA, some with enable, watchdog or reset circuits (see the table below). Picking ...

People have been predicting the demise of low-drop-out linear regulators in cars for many years. Yet low-drop-out (LDO) regulators continue to survive and even thrive because they're cheap and easy to ...

For as versatile and inexpensive as switch-mode power supplies are at all kinds of different tasks, they’re not always the ideal choice for every DC-DC circuit. Although they can do almost any job in ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...
