MR's many type-TAPCON 260-D voltage regulators delivered to DEWA (Dubai Electricity and Water Administration) have successfully passed an important test. At ABB in Baden (Switzerland) they passed the ...

Picotest recently released a new family of signal injectors aimed atimproving voltage regulator, LDO, and power supply testing accuracy. The family consists of two injection transformers, a DC bias ...

Output impedance is the key to testing filter and regulator phase margin, even when the control loop is inaccessible. Many voltage regulators are of the fixed output variety and include the voltage ...

Schweitzer Engineering Laboratories, Inc. has announced its entry into a new market with the release of the SEL-2431 Voltage Regulator Control. The SEL-2431 is compatible with all North American ...

It couldn’t be simpler but you have to admit that a small adjustable portable power supply like this one will be really handy. The main part of the PSU is an LM317 linear voltage regulator which we’re ...

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 ...

STMicroelectronics’ L99VR03 300mA low-dropout regulator provides resilient and efficient power, with a wide input-voltage range.

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 ...

A regulator is a closed-loop feedback system. For the LDO to be stable, the phase margin must be positive. In other words, at unity gain crossover frequency of the gain curve, the phase of the system ...

Pacific Gas & Electric’s state regulator will inspect welds and test segments of a San Bruno, Calif., pipeline in search of similarities with the gas pipe that blew up. The utility began exhuming the ...
