Dimensioning Information on External Components
The input capacitor
C
I
is necessary for compensation of line influences. Using a resistor
of approx. 1
in series with
C
I
, the oscillating of input inductivity and input capacitance
can be damped. The output capacitor
C
Q
is necessary for the stability of the regulation
circuit. Stability is guaranteed at values
C
Q
22
μ
F and an ESR of
5
within the
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:
Overload
Over-temperature
Reverse polarity
