T-3 (TO-92) shutdown function is provided to cut the supply current to less than 0.5 µA. The TMP35 is functionally compatible with the LM35/LM45 The TMP37 is intended for applications over the range of 5°C and provides a 250 mV output at 25°C. The TMP35 reads to 100°C and provides an output scale factor of 20 mV/°C. The temperatures from 10°C to 125°C. The TMP36 is specified from TMP37 provides a 500 mV output at 25°C. Operation extends −40°C to +125°C, provides a 750 mV output at 25°C, and to 150°C with reduced accuracy for al devices when operating operates to 125°C from a single 2.7 V supply. The TMP36 is from a 5 V supply. functional y compatible with the LM50. Both the TMP35 and The TMP35/TMP36/TMP37 are available in low cost 3-lead TMP36 have an output scale factor of 10 mV/°C. TO-92, 8-lead SOIC_N, and 5-lead SOT-23 surface-mount packages.
