operating temperature range.
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 incorporates a number of internal circuits for protection against:
