Mii 42141 POSITIVE HIGH TEMPERATURE REGULATOR + 5 VOLTS Features: Applications: • • • • • • • 200°C Operation Output noise typically less than 3µv Output current up to 150 mA Input voltage up to 30V Internal short circuit protection, foldback and current limiting MICROIRCUITS DIVISION Down hole oil exploration Military & high reliability applications where a hermetically sealed product for harsh environments is required DESCRIPTION This regulator is fabricated using hybrid techniques and will operate at temperatures up to 200°C. This device is complete with internal short circuit protection, which includes voltage shutdown and current foldback. It is strongly recommended that input and output capacitors be added as close to the case as possible. A 2µf capacitor should be added to the input and a minimum of 1.5µf should be added to the output. See typical connection diagram.
