DESCRIPTION
The 42117 series of fixed voltage regulators covers the output voltage range from -5 VDC through -30 VDC. These voltage
regulators are fabricated using hybrid techniques and will operate at case temperatures up to +200
°C. These devices are
complete with internal short circuit protection, which includes voltage shutdown and current foldback.
It is strongly
recommended that input and output capacitors be added as close to the case as possible. A 2f capacitor should be added
to the input and a minimum of 1.5f capacitor should be added to the output. See typical connection diagram below.
