Digitale Armbanduhr (mit ICM 7502)

The first part of this article dealt with universal, variable voltage regulators, and in particular the 723. The second part discusses the three-pin, fixed voltage IC regulators. These were first introduced as `on-card` stabilizing for TTL circuits, and thus the first generation of these IC`s were 5 V regulators. Now whole families of three-pin regulator IC`s have been introduced with a wide choice of preset output voltages. This article deals with applications of these regulators, and also with ways of extending their voltage and current capability.
