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.
