- Figure 1. Hysteresis components R1 and R2 tie to the unregulated supply, causing the comparator's switching point to vary with the power supply
- Figure 2. Resistor R5 and an ORing diode isolate the hysteresis circuit from the power supply and keep the switching point constant no matter how the power supply changes
- Figure 3. The internal design of the LM193 comparator requires that you keep the input pins 2 V below the positive rail
