SGS Thomson Microelectronics – datasheet pdf

The adjustment terminal of the regulator can be bypassed to achieve very high ripple rejection. This site uses Dafasheet to reduce spam. Quote and Order boards in minutes on https: Because you like many circuits to make on your working. We use only 2 resistors to control the output voltage.

If you want to try it. The LM voltage regulators can provide up to 1. We ml350 many ways to make it. Leave a Reply Cancel reply. In addition, it uses internal current limiting, thermal shutdown, and safe mode. We can use the LM on a wide variety of applications.

The LM is best for you.

lk350 No protection diodes are required for output voltages of less than 25V or greater than 10 uF capacitance. Plan to be about 3V about the desired output voltage. Also, its pin output connects the heatsink surface.


Lm35 the list below you may like it. This is an LM Datasheet. 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.

Please update your bookmarks. As in the LM pinout above. Where greater output current is required, the LM series regulators are suitable up to 3A and the LM series voltage regulators for up to lm3550 of output.

See the voltage regulator datasheets above for specific details regarding the dropout voltage and heatsink requirements. An optional output capacitor can be added to improve transient response.

For example A simple adjustable switching regulator. It looks much like the popular LM You see LM circuit below. Which it looks like a popular LM 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.

A programmable output regulator. Learn how your comment data is processed. You can buy at mouser.

The dropout voltage of the IC regulator is about 1. If you are looking for 3A adjustable power supply. Since it has high current datashet 3A, we must mount the LM on the large heatsink. Normally, no capacitors are needed unless the device is situated more than mm 6 inches from the input filter capacitors in which case an input bypass capacitor is required. Solid tantalum capacitors datashdet be used on the voltage output to improve the ripple rejection of the voltage regulator.


To determine the output voltage, enter values for the program R 1 and set R 2 resistors and hit the “Calculate” button. Because it is the adjustable three terminal positive voltage regulator.

But It can supply the output current over 3. The LM may be boring for you.

Over and Under voltage protection of electrical appliances July 11, Simple Crystal oscillator Circuit using 74LS04 November 17, Transistor stereo bass booster September 15, A precision current regulator.

Last update 6 January However, other values such as or ohms can also be used for R 1. Many electronics circuits and projects for learning in simple ways.

You don’t want to use too high an input voltage as the excess will need to be dissipated as heat through the regulator. We can set the output voltage with only two external resistors.
