[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 ...

Sensibly, there is a transformer in the test setup — an isolation transformer to make it ... The circuit is simple enough: it uses a capacitor, a resistor, and a pair of diodes (one of them ...

Using a 6.3V zener diode is common because it is the most stable zener diode over time and temperature (Reference 3). The buried-zener diode still requires a rather high 8V, but it is superior in all ...

In place of T2, we make use of Zener diode ... TI’s MSP430 powered with a 3.3V supply voltage, we have used the following data: For the above range, a commonly available Zener diode is the 1N5240 (V Z ...
