.. his results. The circuit, applied as a 4 to 20 mA current mirror, is shown in Figure 1 and discussed in “Combine two TL431 regulators to make versatile current mirror” ( Ref. 1 ). Figure 1. A 4 to 20 mA current mirror with poor ...
.. combining two of the beasties to make a programmable gain current mirror. The choice between the 2.5-V reference voltage TL431 and the 1.24-V TLV431 can be based on their different current and voltage ratings. For current: 1 mA to 100 mA ...
.. 0.5 mJ, and I CMAX(Q1) ≈ 1 A. R 1 , R 2 , and R 3 divide down V C1 . When this reduced voltage reaches 2.5 V, the TL431’s 2.5 V reference starts to sink the current through R 4 , so the voltage at the trigger input of the ...
