HTMOSTM High Temperature Products Preliminary HIGH TEMPERATURE POSITIVE LINEAR REGULATOR HTPLREG FEATURES APPLICATIONS • Specified Over -55 to +225°C • 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 operate over an extremely wide temperature range of -55 to +225°C. The regulator's control circuit is fabricated with Honeywell’s dielectrically isolated high-temperature (HTMOS™) process. A silicon-on-insulator MOSFET is the power device. The HTPLREG is designed specifically for severe high-temperature applications such as down-hole oil well, aerospace, turbine engine and industrial control. The HTPLREG is available with a calibrated +5, +12, +10, or +15V output. Output current is 500 mA over the specified temperature range, while quiescent current is 1.5 mA. Internal short circuit protection is provided. All parts are burned in to eliminate infant mortality. The HTPLREG is a high-reliability part designed specifically for applications with an extremely wide operating temperature range.
