REF50D

THIS DOCUMENT IS FOR MAINTENANCE PURPOSES ONLY AND IS NOT RECOMMENDED FOR NEW DESIGNS JUNE 1993 DS2427 - 1.0 REF50Z/REF50D 5V MICROPOWER PRECISION REFERENCE The REF50Z and REF50D are integrated circuits using the bandgap principle to provide a precise stable reference voltage of 5V. There are two package options available: REF50Z in a plastic 3-pin TO-92 and REF50D in a miniature surface mount package (MP8). These references feature a recommended operating current of 60µA to 5mA which make them ideal for all low power and battery applications. FEATURES s s s s s s s s s Low Knee Current - typically 40 microamps Ideal for Battery Operation - 300 microwatts Internally Shaped REF50Z - 3 lead TO-92 Plastic Package REF50D - Miniature Plastic Surface Mount Package (MP8) Tight Initial VREF Tolerance ±1.5% Low Temperature Coefficient Low Slope Resistance Operation over Industrial Temperature Range Fig.1 Pin connection ORDERING INFORMATION Device Type REF50Z REF50D Operating Temperature -40°C to +85°C -40°C to +85°C Package TO-92 MP8 ABSOLUTE MAXIMUM RATINGS Reference current 5mA Operating temperature range: REF50Z -40 to +85°C REF50D -40 to +85°C Storage temperature -55 to +125°C Storage temperature for a max. time of 10ns: within 1.59mm of seating plane 300°C within 0.80mm of seating plane 265°C Fig.2 Internal connections REF50Z/50D ELECTRICAL CHARACTERISTICS Test conditions (unless otherwise stated) Tamb = 25°C, IREF = 150µA Value Characteristics Symbol Min.
