LMz is the constant current source and temperature sensor, can detect temperature that degrees Celsius. Error less than 2 degrees. Easy to use and cheap. Because shaped like a transistor 2N, which we are familiar as well. LM is IC that is used as constant current source and temperature sensor. By there are all four models shaped.
Which can notice at a character end of IC number. We now suggest only LMZ. Which has chassis features as TO92 by Figure 1. Since it is cheap and easy to use. So, widely used in general project. The temperature that IC can be detected in the 0 to 70 degrees Celsius. So the error under 2 degrees.
But if the temperature is more or less than this. May have a higher error. Figure 1 characteristics chassis in a TO92 of LMz. Figure 2 the base circuit of LMz.
As constant the specification of the IC. From such features causes voltage output from IC has characteristics is linear as well.
The value of voltage that drop across the Rset will changes according to temperature, as shown in figure 3. Figure 3 The graph shows the relationship between VR and temperature. When the temperatures rise then the voltage cross the Rset will also high up. Which the values obtained?? Features 1mA to 10mA Operation 0. I always try to make Electronics Learning Easy.

Datasheet Texas Instruments LM334
Current is established with one external resistor and no other parts are required. In addition, reverse applied voltages of up to 20V will draw only a few dozen microamperes of current, allowing the devices to act as both a rectifier and current source in AC applications. The ….
