OVERLOAD_PROTECTION_FOR_SERIES_REGULATOR

For input voltage of 30 to 40 v d-c, output at full load of 3 amp will be held within 99.09% of 28 v. Tunnel diode D4 and transistor Q8 in overload-sensing circuit trigger monostable mvbr Q6-Q7 to remove drive from Q1 until mvbr resets.-J.Takesuye, Tunnel-Diode Sensor Protects Regulator from Short Circuit, Electronics, 38:25, p 75-76.
