Circuit Description

The control amplifier compares a reference voltage, which is kept highly precise by

resistance adjustment, to a voltage that is proportional to the output voltage and drives

the base of the series transistor via a buffer. Saturation control, working as a function of

load current, prevents any over-saturation of the power element. The IC is additionally

protected against overload, overtemperature and reverse polarity.
