AS300

SEMICONDUCTOR AS300 Shunt Temperature Sensor Description The AS300 is a two-terminal integrated circuit temperature sensor. It is a precision-trimmed shunt type regulator that emulates a zener diode in function. Its output voltage is linearly proportional to temperature in Kelvin. The output voltage is calibrated for 3.000 V at 27¡C (300 K) and increases by 10 mV/¡C. The AS300 is available in four packages.The SOT-223 offers a large heat-sink for transferring heat to the die for fast and accurate thermal sensing. The SOT-223 is especially effective at sensing the temperature of hybrid and MCM substrates. The SOT-23 is best-suited for applications requiring a small footprint or precision force/sense metering.
