Some 99 percent of the “design” problems associated with linear and switching regulators can be traced directly to the improper use of capacitors: wrong type, wrong value, or incorrect physical ...

[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a cheap ...

In the old days every instrument or system had a power supply board with discrete, homemade regulators on it to power the system. Then IC’s like the LM7805 series of voltage regulators changed ...

Among regulators, the simplest regulator circuit is for a low-dropout (LDO) voltage regulator whose topology is shown in Fig. 1. As a linear voltage regulator, its ...

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 ...

What are typical applications for a low dropout (LDO) linear regulator? LDO linear regulators are usually employed in systems that require a low-noise power source instead of a switching regulator ...

Figure 1 shows a switching regulator that can generate a lower voltage from a high voltage. In this type of circuit, the bypass capacitor (CBYP) is especially important. It has to support the switched ...

PLANO, Texas--(BUSINESS WIRE)-- Diodes Incorporated (NAS: DIOD) , a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and ...

GaN power transistors can shrink AC‑DC power supplies and cut losses but, to get the best out of them, their gate drive waveform needs careful attention. As a German team pointed out at ISSCC, GaN ...

Energy saving: artist’s impression of the gate material with negative capacitance. (Courtesy: Ella Maru Studio) By exploiting a curious effect called negative capacitance, researchers have designed a ...
