L7905CV 1A Negative Fixed Voltage Regulator

• No external components required• Internal thermal overload protection• Internal short circuit current limiting• Output transistor safe-area compensation• Output voltage tolerance of 2%

This regulator employs current limiting, thermal shutdown and safe-area compensation - making it remarkably rugged under most operating conditions. It is supplied in TO-220 style case. It has a voltage drop of 1.1V and a peak output current of 2.1A.

The manufacturer spec suggests with input between -7V > -35V, output will be -5V +-0.1V. Mine will regulate OK until approx. -9V, then with input any further negative, the output voltage is just the input value +4V. Is this how it's meant to work?
