Here we used a Zener as the reference and thetransistorQ1 as a series regulator doing the hard work. R2 provides bias to turn Q1 on and supply a much smaller current through the Zener D2. If Vout is 5V, the base-emitter volt drop of 0.6V would be added to that, so D2 would need...
A voltage regulator is a 3-terminal device. Pin 1 is the Input Pin. The output voltage of whatever voltage source you want to regulate down (whether it's a transformer, battery, etc.) is fed into this pin. So for instance, if you have 10 volts coming from a transformer that you wan...
When testing the voltage of a voltage regulator, we first check the voltage from the input pin to ground. This is to make sure that voltage is, in fact, being supplied to the regulator. If the regulator isn't receiving sufficient voltage, of course it will not be able to output its ra...

How to get best use from step-down voltage regulatorKeith Bassett
Line/mains voltage is too high to be connected directly to an Arduino. The ADC cannot measure voltages that high. Some sort of pre-scaler is required to...
A voltage regulator is an important component of your car's charging system. As the name indicates, it regulates the amount of voltage produced from the alternator to ensure a consistent voltage to the battery and electrical equipment in your car. The vo
Once you have completed the AC wiring give it all a once-over to make sure you have connected everything properly. When you turn it on the LED display should light up with what the "SET TIME" is configured for. If it starts cycling non-stop then the DIP switches may be incorrectly se...
