Notes: 1) Only in refOUT mode or with external REF less than 2.525 V and greater than
2.475 V. For external REF out of these limits see leaflet. 2) VOUT is linked to VREF, by
conception the difference between these two nodes for IP = 0 is maximum 25 mV,
2.475 V < VOUT < 2.525 V. 3) In RefOUT mode at TA = 25C, 2.475 V< VREF
< 2.525 V. The minimal impedance loading the ref pin should be > 220 kW. Internal
impedance = 600 W. For most applications you need to buffer this output to feed it
into an ADC for example. 4) To overdrive the REF (1.9 V .. 2.7 V) max 1 mA is
needed. 5) IS = IP/NS. 6) Only due to TCR IM.
