Additionally, the negative rail is now regulated and remains fixed and independent of variations in load or input voltage and can be set to any desired voltage within range by choosing a different Zener diode voltage. The same technique can be used to regulate the positive rail if this is mor...
In relatively low current circuits, the trade-off is minimal, but for many modern high current rails, an alternative solution is required. Figure 4 shows an update to Figure 3, showing both the TVS and the added series diode to protect against the reverse polarity connection. Figure 4. ...

How is zener diode fabricated so as to make it a special purpose diode the significance of brekdown votlage explain brielfy with the help of a cirucit di
Step 2: Purpose of Zener DiodeThe primary purpose of a Zener diode is to provide voltage regulation. It maintains a constant output voltage despite variations in the input voltage or load current. This is crucial in electronic circuits where a stable voltage is required. Step 3: Circuit Configu...
Therefore, in order to solve the above concern each diode must be added with a series resistor, appropriately calculated for the freewheeling application as per the given parameters. Connecting Diodes in Parallel The procedure of connecting diodes in parallel correctly may be done in the following ...
This electronics video tutorial provides a basic introduction into transistor base bias circuits. It explains how to find the DC load line and the Q-point values for Ic and Vce. People also ask ! How can I choose a suitable Q point on the load line of transistor?
That's it, it's as simple as that, once you do it, the output voltage would get adjusted to that particular value permanently. But do remember to remove the zener diode if there's any at the output of the power supply before you do the above procedures....
Optionally, a Schottky diode DCHG can be used which prevents reverse-flow of current during turn-off. If this diode is used, VDD in the following equations should be replaced with (VDD−VF) to account for the diode's f...
