| 42095 NEGATIVE HIGH TEMPERATURE REGULATOR Mii HYBRID MICROELECTRONICS PRODUCTS DIVISION Features: * * * * * Output current to 1.5 amps Input voltage to -30V Internal short circuit protection, foldback and current limiting Storage Temperature +250C 200C Operating temperature Applications: * * * * * Logging while drilling Measuring while drilling (down-hole applications) Other harsh environments Used as military and industrial devices Designed for use in high temperature environments DESCRIPTION The 42095 series of regulators covers the voltage range from -5 VDC through -30 VDC. These regulators are fabricated using hybrid techniques and will operate at temperatures up to +200C case. These devices are complete with internal short circuit protection which includes voltage shutdown and current foldback. The 42095 series regulators normally do not require any additional components. However, for good design practice, an external filter cap should be installed at the input, as close to the case as possible.
