The switching-versus-linear regulators debate is rather like ac versus dc power. Most people take it to be about which is best, and that has been decided, so discussion over. The traditional, widely ...

Editor's note: Designers at all levels of power management design will find this application article both educational for those not very familiar with these basic concepts as well as an excellent ...

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 ...

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 ...

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 ...

Micrel’s latest low noise voltage regulator combines the low noise and fast transient response characteristics of a traditional low dropout regulator with a power efficiency only achievable with a ...

The output ripple of a standard isolated dc-dc converter is between 0.5% and 1% of its nominal output voltage. For applications requiring a lower output ripple, linear voltage regulators can reduce a ...

Perhaps the simplest way to regulate a DC voltage is using a voltage divider and/or an active device like a Zener diode. Besides simplicity, they have the additional advantage of not being ...

Numerous electronic components like phase-lock loops, FPGA transceivers, and precision op-amps require a low noise voltage rail in order to operate as specified. More often than not, when a need for a ...

A 2A, 58VIN step down switching regulator from Linear Technology features Burst Mode operation, which the company claims can maintain quiescent current at less than 85µA. The LT3980 operates within a ...
