LM Datasheet 3A adjustable Regulator |

Plan to be about 3V about the desired output voltage. Which it looks like a popular LM Although the surge is very short in duration, there is enough energy to damage parts of the regulator IC. The LM may be boring for you. For example A simple adjustable switching regulator.

Also, its pin output connects the heatsink surface. Because it is datashest adjustable three terminal positive voltage regulator. Basic to use LM We love it because easy to use. Even small capacitors can have a low enough internal series resistance to be able to deliver 20A spikes when shorted.


Please update your bookmarks. However, other values such as or ohms can also be used for R 1. This is an LM Datasheet. You can buy at mouser.

National Semiconductor

Created 28 July If you are looking for 3A adjustable power supply. We can use the LM on a wide variety of applications. Solid tantalum capacitors can be used on the voltage output to improve the ripple rejection of the voltage regulator.

We have many ways to make it.

LM317 / LM338 / LM350 Voltage Regulator Calculator

We can set the output voltage with only two external resistors. Over and Under voltage protection of electrical appliances July 11, Simple Crystal oscillator Circuit using 74LS04 November 17, Transistor stereo bass booster September 15, The adjustment terminal of the regulator can be bypassed to achieve very high ripple rejection. Last update 6 January No protection diodes are required for output voltages of less than 25V or greater than 10 uF capacitance.

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. As in the LM pinout above.

This site uses Akismet to reduce spam. We use only 2 resistors to control the output voltage.


Normally, no capacitors are needed unless the device is situated more than mm 6 inches from the input filter capacitors in which case l3m50 input bypass capacitor is required. You don’t want to use too high an input voltage as the excess will need to be dissipated as heat through the regulator.

It looks much like the popular LM With connecting a fixed resistor between the adjust and output.

The dropout voltage of the IC regulator is about 1. 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. Learn how your comment data is processed. Many electronics circuits and projects for learning in simple ways.

Quote and Order dataeheet in minutes on https: In addition, it uses internal current limiting, thermal shutdown, and safe mode. Because you like many circuits to make on your working. A precision current regulator.

The LM voltage regulators can provide up to 1.
