.. were both absolutely correct. Table 6.6 in the TL431 datasheet reveals a maximum reference-voltage error of up to 2 mV per volt of cathode-to-anode voltage swing, consistent with the mediocre 20 V/40 µA = 500k active impedance he ... .. is to say, just how “constant” is their output held against changes in applied voltage? Frequent and expert Design Idea (DI) commentator Ashutosh Sapre was kind enough to measure this parameter for a design of mine and share ...
.. is withdrawn first, and then the 5-V supply. Hence, one push button does both (sequential) ON and OFF functions. This Design Idea (DI) is intended for MCU-based projects. No additional components/circuitry are needed to implement this ...

.. R 4 in response to an input change. V OUT now settles to ½ LSbit of a 16-bit source in 2.5 ms. Changing C 3 to 510 pF (10% COG/NPO) reduces that time to 1.4 ms. Smaller values of C 3 provide little further advantage. The V OUT ... .. the output of A1 react to this while driving a hypothetical U1, which is capable of producing an anomaly-free ( Ref. 4 ) 0-volt output. Figure 3. V OUT and A1’s output from Figure 1 react to a step change in V DAC . Even though V OUT ... .. Woodward’s “Ignoring the regulator’s reference” ( Ref. 1 ) Design Ideas (DI) (see Figure 1) is an excellent, working example of how to include a circuit in the feedback loop ...
