HTMOSTM High Temperature Products Advance Information HIGH TEMPERATURE NEGATIVE LINEAR REGULATOR HTNLREG FEATURES APPLICATIONS * Specified Over -55 to +225C * Down-Hole Oil Well * Output Current to -300 mA * Avionics * Adjustable or Calibrated -15, -10, and -5V Output * Turbine Engine Control * Input Voltage to -28V * Industrial Process Control * -3.0 mA Quiescent Current * Nuclear Reactor * Current Limit and Foldback Short Circuit Protection * Electric Power Conversion * Hermetic 4-Pin Package * Heavy Duty Internal Combustion Engines GENERAL DESCRIPTION The HTNLREG is a hybrid linear regulator designed to operate over an extremely wide temperature range. The regulator's control circuit is fabricated with Honeywell's dielectrically isolated high-temperature (HTMOSTM) process. A silicon-on-insulator MOSFET is the power device. The HTNLREG is designed specifically for severe hightemperature applications such as down-hole oil well, aerospace, turbine engine and industrial control. The HTNLREG is available with a calibrated -5, -10, or -15V output. Output current is -300 mA over the specified temperature range, while quiescent current is -3.0 mA. Internal short circuit protection is provided which includes current limit and foldback. All parts are burned in at +250C to eliminate infant mortality. Typically, parts will operate up to +300C for a year, with derated performance. The HTNLREG is a high-reliability part designed specifically for applications with an extremely wide operating temperature range.
