To prevent this, a diode such as a 1N can be connected across the I. If you spend over Posted by Rob Haywood on Tuesday, 28 June International orders can only be shipped to the registered card address.

Notice that C1 and C2 are much smaller than would be found in discrete component power supply. Voltage drop out 1A: Hero Banned May 24, Email to a Friend. To participate you need to register.

ap Ic, ap Ic Suppliers and Manufacturers at

In modern linear I. Switched Mode Power Supplies. No matter how many uc transistors, you will still be dissipating the same amount of heat. The IC can provide up to mA and is suitable for a wide input voltages. In Relation to the 78xx series of Voltage Regulators: Hi Peter, You can run the amp kit from as little as 2V, however the higher the supply the better the quality. International orders may be charged import duty dependant on local import laws and duty rates.


Hero Banned May 27, They can be used for regulating negative supply or dual supply rails.

Many thanks in advance. Further Information For information about all of the delivery options we offer click here. Posted by Michael Lockhart on Thursday, 9 November I would looking at modifying an old 12V car battery charger – these usually give about 15 volts at around 4 to 6 amps which is ideal for making a 12v PSU. Too high an input voltage and power is wasted, this is bad for battery life in portable equipment and bad for reliability in high power equipment as more heat means a greater possibility of 78102.

Potentiometer Questions Started by norbss Yesterday at The is an old, inefficient part.

The reason is that when unplugging or connecting multi-way connectors there is 780012 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 780112 connection or disconnection process. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. The 5A delivered to the load has to go through the pass transistor.

Any positive voltage spikes greater than oc maximum permitted input voltage around 35V or 40V or any negative spikes greater than Datasheets, Manuals or Parts. Be the first to review this product Email to a Friend. Most audio amplifiers reject mains hum that is from the power supply so that they don’t need a regulator.

12 Volts 5A voltage regulator circuit problem

The IC can if up to mA and is suitable for a wide range of input voltages. Its cheaper to buy a battery charger than a 50 or 60W transformer.

Each volt of difference between the input voltage to the regulator and the 12V output represents 5 Watts of heat which must be removed. Shielded audio cable should always be used for feeding a signal to an amplifier. The output from the regulator would then be connected to the positive supply on the 70812. The availability of regulator circuits in 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. Regulated Power Supplies 3.

This may be either because the system is still connected to the mains supply or because capacitors in the main supply are not fully discharged.

Heromay be you can help me with this informationplease since you were 87012 one who led me to the link.
