Current Limiter Circuit and Output Stage
In source mode, when Q3 turns on and current flows into the load resistor, a voltage difference occurs across RSC,
turning on Q1 and activating the current limiter.
In sink mode, Q4 turns on to develop a voltage difference of the polarity opposite to that in the source mode across RSC,
thus turning on Q2 and activating the limiter.
A RSC can be use to set the maximum output current, but the maximum output current will vary slightly depending on
the VBE temperature characteristics of the transistor.
