2.7V, SOT-23 or TO-92 Temperature Sensor
General Description
The LM60 is a precision integrated-circuit temperature sensor
that can sense a −40°C to +125°C temperature range while
operating from a single +2.7V supply. The LM60's output volt-
age is linearly proportional to Celsius (Centigrade) tempera-
ture (+6.25 mV/°C) and has a DC offset of +424 mV. The
offset allows reading negative temperatures without the need
for a negative supply. The nominal output voltage of the LM60
ranges from +174 mV to +1205 mV for a −40°C to +125°C
temperature range. The LM60 is calibrated to provide accu-
racies of ±2.0°C at room temperature and ±3°C over the full
−25°C to +125°C temperature range.
The LM60's linear output, +424 mV offset, and factory cali-
bration simplify external circuitry required in a single supply
environment where reading negative temperatures is re-
quired. Because the LM60's quiescent current is less than
110 μA, self-heating is limited to a very low 0.1°C in still air in
the SOT-23 package. Shutdown capability for the LM60 is in-
trinsic because its inherent low power consumption allows it
to be powered directly from the output of many logic gates.

... Note 9: Nonlinearity is defined as the deviation of the output-voltage-versus-temperature curve from the best-fit straight line, over the device's rated temperature range. Note 10: Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output due to heating effects can be computed by multiplying the internal dissipation by the thermal resistance. ...

... This is especially true when a small (Surface-Mount) part is wave-soldered; allow time for stress relaxation to occur. The majority of the drift will occur in the first 1000 hours at elevated temperatures. The drift after 1000 hours will not continue at the first 1000 hour rate. ...
