REF19x Series management should still be exercised. A short, heavy, low dc resistance (DCR) conductor should be used from the V Sense Point S, where the collector of Q1 connects to the load, Point F. Because ...

Although this concept is simple, some cautions are needed. Because the lower reference circuit must sink a small bias current from U2 (50 μA to 100 μA), plus the base current from the series PNP output transistor in U2, either ...

REF19x Series Using dissimilar REF19x series devices with this configuration allows logic selection between the U1/U2-specified terminal voltages. For example, with U1 (a REF195) and U2 (a REF196), as noted in the table in Figure 30, changing the CMOS-compatible V ...
