It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...

[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 ...

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 ...

My recent columns discussed the physics and applications of discrete-zener-diode references, and the conclusion they reached is that discrete zener diodes make poor references because of tolerance ...
