The LM The third terminal allows either the temperature coefficient to be minimized or the reference voltage to be adjusted without changing the temperature coefficient. Because it operates as a shunt regulator it can be used equally well as a positive or negative reference. For more demanding precision reference applications requiring very low initial tolerance and temperature coefficients, consult the LT data sheet. At least one model within this product family is in production and available for purchase.

The LM is a precision 2. It has a dynamic Impedance of 0. It can also operate on high frequency upto Hz. The LM acts like a 2. Two of which are anode and cathode just like any other Zener diode and the third pin is the adjacent pin as show in the pinouts above. This third pin can be used to adjust the breakdown voltage and temperature coefficient of the IC.
The IC is used in application where a precise 2. As you can see the third pin being an optional pin is not used in this circuit, you can refer to the datasheet at the bottom of this page to know the other possible application circuits for this IC. The advantage of LM over ordinary Zener diode is it low impedance value 0. Further the third pin on LM improves the performance of the circuit by optimizing the breakdown voltage and temperature coefficient value.
The IC is commonly used in 5V digital systems to provide 2. Subscribe to stay updated with industry's latest Electronics components and news. LM 2. Alternative 2. The dimensions of TO package is shown below.
