Performance is comparable to that of combined discrete and monolithic circuits, with load regulation of 0.01%, line regulation of 0.05%, ripple rejection of 0.1%, and output ripple and noise of 1 mV. Output is 1 A at 5 V. Foldback short-circuit protection is provided by Tr4, with maximum current determined by value of R. C2, which can be 100 μF, gives extra ripple rejection by introducing more AC feedback into loop.TIP32A is plastic series transistor, and is not critical; many other types will work equally well.-K. W. Mitchell, High Performance Voltage Regulator, Wireless World, May 1976, p 83-84.
