TM HTMOS High Temperature Products Preliminary HIGH TEMPERATURE POSITIVE HTPLREG LINEAR REGULATOR FEATURES APPLICATIONS Specified Over -55 to +225C Down-Hole Well Output Current up to 500 mA Avionics Calibrated +15, +12, +10, and +5V Output Turbine Engine Control Input Voltage up to 28V Industrial Process Control 1.5 mA Quiescent Current Nuclear Reactor Current Limit Short Circuit Protection Electric Power Conversion Hermetic 4-Pin Power Package Heavy Duty Internal Combustion Engines GENERAL DESCRIPTION The HTPLREG is a hybrid linear regulator designed to The HTPLREG is available with a calibrated +5, +12, +10, or operate over an extremely wide temperature range of -55 +15V output. Output current is 500 mA over the specified to +225C. The regulator s control circuit is fabricated with temperature range, while quiescent current is 1.5 mA. Internal Honeywells dielectrically isolated high-temperature (HT- short circuit protection is provided. All parts are burned in to MOS) process. A silicon-on-insulator MOSFET is the eliminate infant mortality. The HTPLREG is a high-reliability power device. The HTPLREG is designed specifically for part designed specifically for applications with an extremely severe high-temperature applications such as down-hole wide operating temperature range. oil well, aerospace, turbine engine and industrial control.
