IC references are popular with circuit designers because they are accurate and exhibit low drift. Some of my future columns will cover the three types of IC references: buried zener, bandgap, and XFET ...

For the longest time, Zener diode regulators have been one of those circuits that have been widely shared and highly misunderstood. First timers have tried to use it to power up their experiments and ...

Semtech Corp. has received MIL-PRF-19500/406 qualification from Defense Supply Center Columbus, (DSCC) of its brand new 1.5W Zener diode voltage regulator platform. Semtech Corp. has received ...

There are many small applications where it would be preferable to power a device directly from an RS232 (V.24) interface, avoiding a mains power supply. Most ICs require 5 V, and the interface can ...

Perhaps the simplest way to regulate a DC voltage is using a voltage divider and/or an active device like a Zener diode. Besides simplicity, they have the additional advantage of not being ...

New programmable shunt regulators from Diodes are said to raise the efficiency of low power systems due to a minimum cathode current for regulation of typically only 40µA. According to Diodes, the ...

In the realm of modern electronics, semiconductor diodes have emerged as fundamental components with diverse applications. One of their pivotal roles lies in the fields of rectification and voltage ...

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 ...
