The idea of course is to implement a known current limit when that is not built into the voltage regulator, especially when we want some adjustment too.A single bipolar with current sense resistor (any maybe a diode) can sense the current level and provide "OR'ed" feedback to the voltage...
In operation, the current feedback signal 6a and the voltage feedback signal 7a are calculated in an output calculator 4. When the output of a DC circuit exceeds a limit value, a thyristor control signal 3a is corrected by the signal 4a of the calculation 4 and the output voltage of the...
VOUT1 must be set to a voltage at least one diode drop higher than 8.55 V (the maximum VCC voltage) if D2 is used to supply bias current. 8.2.2.3 Application Curves Figure 8-9. Steady State Waveform (VIN = 48 V, IOUT1 = 100 mA, IOUT2 = 200 mA) Figure 8-10. Step Load ...
