Mii 42094 POSITIVE HIGH TEMPERATURE REGULATOR Features: Applications: • • • • • • • • • • Output current to 1.5 amps Input voltage to 38V Internal short circuit protection, foldback and current limiting Storage Temperature 225°C 200°C Operating Temperature Output voltage to 30 VDC HYBRID MICROELECTRONICS PRODUCTS DIVISION Logging while drilling Measuring while drilling (down-hole applications) Other harsh environments Designed to use in high temperature environments 200°C DESCRIPTION The 42094 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 200°C case. These devices are complete with internal short circuit protection which includes voltage shutdown and current foldback. The 42094 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.
