Description:

 LM338T is a three terminal positive adjustable voltage regulator IC available in TO-220 package. The IC provides stable output voltage for example if the user set its output on 5V then it will provide stable 5V output no matter if the input voltage is fluctuating. But the user or designer of the circuit has to keep one more thing in mind that the input voltage must be 2V to 3V higher than the output voltage in any condition. To solve this problem the user should provide higher input voltage than the output for example for 5V output the input voltage can be 12V or more so if the input voltage fluctuates 3V to 5V then we still get a stable 5V at the output. One best example of this can be a solar panel that changes the output voltage frequently on a partly cloudy day.

This IC is adjustable from 1.2V to 32V DC and the maximum input voltage can be applied to the IC is 40V. LM338T can be easily used in the place of LM317 if there is a requirement for higher amperes, the IC Is capable to deliver load of up to 5A output current. However, this can also be done by using one or two high current transistors with the LM317 IC but using LM388T is still a good option if the output current requirement is under 5A.

Moreover, LM338T requires very low external components because all the important circuitry is built inside the IC and hence at the output it requires only two capacitors (in some conditions), and two external resistors to adjust the output voltage. There is also an output voltage calculator available online for the IC which shows the value of the resistor to be used for a specific output.
