42118 POSITIVE HIGH TEMPERATURE FIXED VOLTAGE REGULATOR Designed for use in high temperature environments Mii HYBRID MICROELECTRONICS PRODUCTS DIVISION Features: • • • • • Operating temperature +200ºC Output current to 1.0 A Input voltage to +30 V Internal short circuit protection, foldback and current limiting Isolated TO-258 package Applications: • • Military and Hi Rel Industrial harsh environment applications where hermetically sealed product is required Down hole applications DESCRIPTION The 42118 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 temperatures up to +200ºC. These devices are complete with internal short circuit protection, which includes voltage shutdown and current foldback. The 42118 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.
