Circuit Description

The control amplifier compares a reference voltage to a voltage that is proportional to the

output voltage and drives the base of the series transistor via a buffer. Saturation control

as a function of the load current prevents any oversaturation of the power element. The

IC also includes a number of internal circuits for protection against:

•

Overload

•

Overtemperature

•

Reverse polarity
