This circuit, with output of 1.5 A, was found in a magazine 73 of the 90s. The integrated circuit is from the time and must be mounted in a heat sink.
This circuit was found in a 1987 publication, but it can still be easily assembled today as the...
This circuit uses a common diode as sensor. The output goes from 0 to 10 V with the temperature change in...
This circuit, from an old publication, can also use modern transistors. Note that the unit is...
