International orders can only be shipped to the registered card address. If a circuit panel is unplugged whilst the supply is live it is possible that the ground connection to the I.

The maximum input voltage listed in table 1 shows that there is plenty of allowable difference between maximum and minimum input voltage, however it should be remembered that the higher the input voltage for a given output, the more power will need to be dissipated by the regulator.

7812 Regulator

Short the input snd if the hum goes away then it is probably mains hum picked up by unshielded input wires. The 5A delivered to the load has to go through the pass transistor. Mains hum is usually picked up if unshielded input wires are used.

To prevent this, a diode such as a 1N can be connected across the I. Hi Peter, You can run the amp kit from as little as 2V, however the higher the supply the better the quality. Be the first to review this product.


The other alternative is a switcher, Could you use an PSU from an old iv You must have JavaScript enabled in your browser to utilize the functionality of this website. Notice that C1 and C2 are much smaller than would be found in discrete component power supply.

By continuing to use this site, you are consenting to our use of cookies. If you spend over Each volt of difference between the input voltage to the regulator and the 12V output represents 5 Watts of heat which must be removed. Switched Mode Power Supplies. The IC can provide up to mA and is suitable for a wide input voltages.

We do not charge a 780012 or handling fee for this service, and you will receive an email when your order has been processed, you can collect half an hour after receipt of this email. The output from the regulator would then be connected to the positive supply on the module.

Be the first to review this product Email to a Friend. C2 is no longer a traditional filter capacitor but is there to improve the transient response, protecting against sudden changes in mains or load conditions e. The reason is that when unplugging or connecting multi-way connectors there is no guarantee in which order individual pins are connected or disconnected, and this can lead to unexpected short circuit or open circuit faults occurring momentarily during the connection or disconnection process.

The criteria for using heat sinks is the same as that for power transistors, discussed in Amplifiers Module 5. Integrated circuit regulators are readily available in a variety of current and voltage ratings for shunt or series applications as well as complete switched mode types. Hero Banned May 27, Sign up to our newsletter for promotions. No matter how many pass transistors, you will still be dissipating the same amount of heat.


There are various ranges, in several package types available from many component manufacturers, some of which are shown in Fig.


The L is a simple 3 pin voltage regulator in a TO package. These charges are usually billed to you directly from UPS. Alternatively you can choose the free collection option and have your own courier collect it from 780012.

For a list of postcodes that will be charged the remote location rate click here. The use of linear regulator I. If you spend between 40 and lc – It is now quite rare to find regulators in the truly discrete forms described in PSU Modules 2.

You haven’t said what the PSU is for? Shielded audio cable should always be used for feeding a signal to an amplifier.

The use of these capacitors, which with the values shown will be polarised tantalum types and although not strictly 70812 in all circuits, are recommended to ensure maximum stability, preventing any tendency of the I.
