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. The 42117 series
voltage regulators normally do not require any additional components. However, for good design practice, an external filter
cap of 2F should be installed at the input, as close to the case as possible.
