Description of Options
-9 Extended Temperature Range
This option defines an extended temperature range as
specified in table 8.
P Potentiometer
Note: Option P is not recommended, if several regulators are
Positive Switching Regulators
The switching characteristics of the option D output are shown
in fig. Definition of V t and V H .
The voltage V t can be externally adjusted by a trim
potentiometer. The hysteresis V H of V t is <2%. Pin D stays low
for a minimum time t low min , in order to prevent any oscillation. V t
can be set to a value between V i min and V i max . Note that the
JFET becomes conductive, when V D exceeds approx. 7 V.

operated in parallel connection.
Option P excludes R function; the R-input (pin 16) should be
left open-circuit. The output voltage V o can be adjusted in the
range 90 – 110% of V o nom .
However, the minimum differential voltage ? V i o min between

exceed the length of approx. 5 m in total. The fundamental
wave (approx. 120 kHz) of the reduced interference voltage
between Vi+ and Gi– has, with an input line inductance of
5 μH, a maximum magnitude of 4 mVAC.
The input impedance of the switching regulator at 120 kHz is
about 3.5 ? . The harmonics are small in comparison with the
fundamental wave.

With option L, the maximum permissible additionally
superimposed ripple v i of the input voltage (rectifier mode) at
a specified input frequency f i has the following values:
v i max = 10 V pp at 100 Hz or V pp = 1000 Hz/ f i ? 1V

Option C protects the load against power supply malfunction.
It is not designed to sink external currents. A fixed-value
monitoring circuit checks the output voltage V o . When the
trigger voltage V o c is reached, the thyristor crowbar triggers

the input voltage. In case of a defect switching transistor, the
internal fuse prevents excessive current.
Note : The crowbar can be reset by removal of the input voltage
only. The inhibit signal cannot deactivate the thyristor.
