42094 Mii POSITIVE HIGH TEMPERATURE REGULATOR MICROPAC MICROCIRCUITS PRODUCTS DIVISION Features: Applications: * * * * * * * * * * Output current to 1.5 amps Input voltage to 38V Output voltage to 30V Internal short circuit protection, foldback and current limiting Storage Temperature 225C 200C Operating temperature Logging while drilling Measuring while drilling (down-hole applications) Other harsh environments Designed for use in high temperature environments 200c 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 200C case. These devices are complete with internal short circuit protection which includes voltage shutdown and current foldback. It is strongly recommended that input capacitors be added as close to the case as possible. A 2f capacitor should be added to the input and a minimum of 1.5 f capacitor should be added to the output. See typical connection diagram.
