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 ...

Designers frequently use linear regulators to postregulate switching-regulator outputs. The benefits of this approach include improved stability, accuracy, and transient response, along with lower ...

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 ...

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 ...

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 ...

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 ...

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 LTC7801 is a high voltage nonisolated synchronous step-down switching regulator controller in compact 24-lead packages that drives an all N-channel MOSFET power stage. Its 4V to 140V (150V abs max ...
