HYBRID MICROELECTRONICS PRODUCTS DIVISION
Features: • • • • • Operating temperature +200°C Output current to 1.0 A Output voltage to –30 V Internal short circuit protection, foldback and current limiting Isolated TO-258 package
Applications: • • Down hole Harsh environment application
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 2µF should be installed at the input, as close to the case as possible.
