The digital low-dropout (LDO) linear regulator is one of the latest innovations in the power industry, bringing telemetry and adjustability to a linear power supply in a very small footprint. The ...

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 ...

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 ...

Supply rejection for a linear regulator is just as critical as output voltage noise. With poor supply rejection, even the lowest noise regulator will pass signal through to the output, and this can ...

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 ...

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 ...

A quiet, well regulated supply is important for optimum performance in a number of circuit applications. Voltage controlled oscillators (VCOs) and precision voltage controlled crystal oscillators ...
