Understanding Linear Power Supply Specifications Introduction to Power Supply Specifications At first glance, a variable DC power supply appears to be a fairly simple device. However, it is a sophisticated, accurate, electrically-rugged workhorse. It must reliably deliver voltage and current that is stable, precise, and clean, no matter its load—resistive, inductive, capacitive, low
designed into the power supply, certain basic precautions must be observed when connecting it for use on the lab bench or as a controlled power supply. This chapter describes basic operation of linear power supplies and gives
The op amp is one of the basic building blocks of linear design. In its classic form it consists of two input terminals, one of which inverts the phase of the signal, the other preserves the phase, and an output terminal. The standard symbol for the op amp is given in Figure 1.1. This ignores the power supply terminals, which are obviously required for operation. Figure 1.1: Standard op amp

As we saw earlier, this is a fairly well behaved circuit that supplies a nearly constant output voltage over a wide range of currents. However, as we always must, we can do better. A better regulation may
lightweight power supply for a rocket. Linear power supplies had been available for more than thirty years but were not suitable for use on the rocket because of their size and weight. This was in the era of the development of electronics, when the IC, diode and transistor were just mass-produced. Prior to this linear power supplies used valves, which were robust as far as temperature and
