[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated ... Essentially, this transistor is being used as a poor-quality Zener diode. At normal temperatures, the pass ...

You develop the reference-design procedure with a zener diode; the zener's simplicity illustrates the design procedure, and its problems make you appreciate IC references. The circuit specifications ...

An uncomplicated circuit application of a ZD is the common shunt voltage regulator. If you have a Zener diode (ZD) of unknown characteristics or if you want to use reverse-biased transistor junctions ...

[James Lewis] does an experiment with a regulator circuit with an ESP8266 after a short introduction to Zener diodes themselves. For the uninitiated, the Zener diode can operate in the reverse ...

While a Zener diode ... of all voltage-regulator circuits, and can provide higher current with the addition of an external p-channel FET. By removing R2 (and shorting R1), the circuit will provide ...

A transient-voltage-suppression diode macromodeloffers greater accuracy than a standarddiode SPICE model. SPICE circuit simulations ... devices and load switching. Zener and TVS avalanche diodes ...
