Output Protection and Short Circuit Behaviour
A voltage suppressor diode, which in worst case conditions
fails into a short circuit (or a thyristor crowbar, option C),
protects the output against an internally generated over-
voltage. Such an overvoltage could occur due to a failure of
either the control circuit or the switching transistor. The

output protection is not designed to withstand externally
applied overvoltages.
A constant current limitation circuit holds the output current
almost constant, when an overload or a short circuit is applied
to the output. It acts self-protecting and recovers automatically
after removal of the overload or short circuit condition.
Parallel and Series Connection
Outputs of equal nominal voltages can be parallel-connected.

However, the use of a single regulator with higher output
power, is always the better solution.
In parallel-connected operation, one or several outputs may
operate continuously at their current limit knee-point which will
cause an increase of the heat generation. Consequently, the
max. ambient temperature should be reduced by 10 K.

The inhibit input allows the switching regulator output to be
disabled via a control signal. In systems with several

converters, this feature can be used, for example, to control
the activation sequence of the converters by a logic signal
(TTL, C-MOS, etc.). An output voltage overshoot will not
