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...
When you have tested the charging system of a car fitted with an alternator , and the checks in How to test a car battery point to a fault in the voltage regulator , make sure that you need to replace it. The fault may be elsewhere.
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...

PROBLEM TO BE SOLVED: To provide a voltage regulator for easy replacement of parts and a method for replacing parts of the voltage regulator. A voltage regulator (100) includes a series transformer (1) in which a secondary winding is connected in series to a distribution line (1u, 1v, 1W...
HOW TO TEST ALTERNATOR CHARGING VOLTAGE Most alternators that are charging properly should produce a voltage of about 13.8 to 14.2 volts at idle with the lights and accessories off. Always refer to the vehicle manufacturer's specifications. Many Asian vehicles, for example, have higher charging vo...
Simple Zener Regulator AZener diodeis a type of diode that, when connected in its reverse bias configuration (see below), begins to “break down” or conduct at a specific voltage, called its Zener voltage. Once it starts conducting, there is no stopping the current, so aresistor(R1 shown...
Testing output on a Lucas ACR alternator The three-pin multiple plug has no earth terminal. Switch on the ignition and test the continuity of the leads one by one, by connecting them with the voltmeter to an earth. You should get a reading of battery voltage for each one; if not, there...
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...
While effective, an LDO regulator’s power dissipation can negatively impact a system’s efficiency. The unique voltage input-to-output control (VIOC) pin reduces power dissipation and increases efficiency through a single connection. VIOC introduces automated control of a switching converter to ...
