An electronic circuit used to maintain a level amount of voltage in an electrical line. It eliminates power surges, spikes and brownouts, which can cause harm to sensitive electronics. A voltage ...

Few things beat the ambiance and styling of a classic C3 Corvette. These legendary sports cars drew hot attention on Main Street and racetracks 50 years ago and nothing’s changed since. They still ...

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 ...

Voltage regulators play an important role in many power systems. The first part of this Back to Basics article examines the role of several types of regulators including low-dropout voltage regulators ...

Step-down (buck) voltage regulators have long been the preferred DC-DC conversion electronic workhorse thanks to their inherently high efficiency. Only in buck mode the current is directed to the ...

Power management of battery-powered electronic devices is becoming increasingly more important for the microelectronics industry. This white paper details the difference between low dropout (LDO) ...

Before you can design an adjustable voltage regulator into your circuit, or do a redesign, you need to calculate the values for two resistors. This is not difficult in itself, but actually finding the ...

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 circuit model in Figure 1 captures the important low-frequency behavior of most voltage regulators (Reference 1). Parameters C 2, R 2, and L 2 represent a typical bulk decoupling-capacitor array.
