HTMOS(R) High Temperature Products Preliminary HIGH TEMPERATURE 5.0V VOLTAGE REFERENCE HTVREF05 FEATURES APPLICATIONS * Specified Over -55 to +225C * Down-Hole Oil Well * Optional External Trim * Avionics * 8mA Output Current * Turbine Engine Control * 1.5mA Quiescent Current * Industrial Process Control * Short Circuit Protected * Nuclear Reactor * Hermetic 8-Pin Ceramic DIP * Electric Power Conversion * Heavy Duty Internal Combustion Engines GENERAL DESCRIPTION The HTVREF05 is a precision high-reliability monolithic voltage reference fabricated with Honeywell's dielectrically isolated high-temperature (HTMOS(R)) process. It is designed specifically for applications with extremely wide temperature ranges of -55 to +225C, such as down-hole oil well, aerospace, turbine engine and industrial control. Typically, parts will operate up to +250C, with derated performance. All parts are burned in to eliminate infant mortality. The HTVREF05 provides a high temperature stable 5.0V output, or bandgap reference for external biasing schemes. Output current is 8mA; power supply current is only 1.5mA.
