Abstract
The invention relates to a voltage limiter for a transistor circuit with semiconductors (T.sub.20 and T.sub.21) in the arrangement of a plurality of successive amplifier stages, with a reference element (Zener diode Z.sub.20) and with at least one voltage divider arrangement (voltage divider R.sub.21 /R.sub.22). In accordance with the invention, the reference element (Zener diode Z.sub.20) is disposed downstream of the triggering circuit of the first stage or even closer at the output of the voltage limiter circuit for reducing the oscillation tendency.
