[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 ...

“Chapter 5; Horowitz and Hill”. University students of all subjects will each have their standard texts of which everyone will own a copy. It will be so familiar to them as to be referred to by its ...

Stable regulation of output voltage is an operational imperative of linear regulators. While this topic has been discussed in the past (Reference 1 and Reference 2), this article provides a practical, ...

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 ...

Diodes Incorporated announces the ZXTR2105F regulator that monolithically integrates a transistor, Zener diode and resistor to provide a 5V 15mA output from inputs up to 60V. Diodes Incorporated ...

Low dropout (LDO) regulators play a very important role in the power management of an integrated circuit. As a result, mindful designing and selection of LDO circuits become crucial. This article ...

The power supply for new products is often taken for granted. However, judging from recent experience, it’s clear that the power supply for new industrial equipment or Internet of Things (IoT) ...

Fig. 1: The exciter, with the original RF amplifier section visible at left rear. We don’t need to throw away equipment that is capable of serving for many years to come if it is updated on occasion.
