F of aluminum or tantalum capacitor are commonly used to provide
improved output impedance and rejection of transients.
In operation, the KA350 develops a nominal 1.25V reference voltage, V
REF
, between the output and adjustment terminal. The
reference voltage is
impressed across program resistor R
1
and, since the voltage is
constant, a constant current I
1
then flows
through the output set resistor R
2
, giving an output voltage of
V

Since I
ADJ
current (less than 100
μ
F) from the adjustment terminal represents an error term, the KA350 was designed to mini-
mize I
ADJ
and make it very constant with line and load changes. To do this, all quiescent operating current is returned to the
output establishing a minimum load current requirement. If there is insufficient load on the output, the output voltage will rise.
Since the KA350 is a floating regulator, it is only the voltage differential across the circuit which
is
important to performance,
and operation at high voltage with respect to ground is possible.
Since I
ADJ
is controlled to less than 100
μ
A, the error associated with this term is negligible in most applications.
