We use only 2 resistors to control the output voltage. If you want to try it. Since it has high current over 3A, we must mount the LM on the large heatsink.

National Semiconductor

Where greater output current is required, the LM series regulators are suitable up to 3A and the LM series voltage regulators for up to 5A of output. Last update 6 January Solid tantalum capacitors can be used on the voltage output to improve the ripple rejection of the voltage regulator. No protection diodes are required for output voltages of less than 25V or greater than 10 uF capacitance.


See the list below you may like it. Even small capacitors can have a low enough internal series resistance to be able to deliver 20A spikes when shorted. You can buy at mouser.

Quote and Order boards in minutes on https: But It can supply the output current over 3. The LM is best for you. When external capacitors are used with a voltage regulator it may be necessary to use protection diodes to prevent the capacitors from discharging through low current points into the voltage regulator.

LM Datasheet(PDF) – Motorola, Inc

Basic to use LM We love it because easy to datassheet. You don’t want to use too high an input voltage as the excess will need to be dissipated as heat through the regulator. This is an LM Datasheet. The LM voltage regulators can provide up to 1. Please update your bookmarks.

Over and Under voltage protection of electrical appliances July 11, Simple Crystal oscillator Circuit using 74LS04 November 17, Transistor stereo bass booster September 15, See the voltage regulator datasheets above for specific details regarding the dropout voltage and heatsink requirements.


For example A simple adjustable switching regulator. We have many ways to make it. Many electronics circuits and projects for learning in simple ways. Also, its pin output connects the heatsink surface.

A precision current regulator. Which it looks like a popular LM As in the LM pinout above. In addition, it uses internal current limiting, thermal shutdown, and safe mode.

To determine the output voltage, enter values for the program R 1 and set R 2 resistors and hit the “Calculate” button.

The LM may be boring for you. The dropout voltage of the IC regulator is about 1. Created 28 July Because you like many circuits to make on your working. Because it is the adjustable three terminal positive voltage regulator.

With connecting a fixed resistor between the adjust and output.
