Obsolescence Notice This product is obsolete. This information is available for your convenience only. For more information on Zarlink’s obsolete products and replacement product lists, please visit http://products.zarlink.com/obsolete_products/ DS2442 - 2.2 SR12D 1.2V PRECISION VOLTAGE REFERENCE The SR12D is a monolithic integrated circuit using the bandgap principle to provide a precise reference voltage of 1.23V. This reference device is packaged in a standard SOT-23 small outline package, making it ideal for all surface mount applications. SOT-23 Fig. 1 Pin connections (top view) FEATURES s s s Standard SOT-23 Surface Mount Package Low Knee Current - Typically 80 µA Low temperature Coefficient ABSOLUTE MAXIMUM RATINGS Reference current Operating temperature range Storage temperature range 2.5mA -40°C to + 85°C -55°C to +125°C Fig.2 SR12D circuit diagram Fig.3 SR12D external connections. NOTE: In order to achieve optimum operation, an electrolytic stabilising capacitor (CS > 1µF) should be connected between VREF and 0V as shown in Fig. 3. ELECTRICAL CHARACTERISTICS These characteristics are guaranteed over the following conditions (unless otherwise stated): Tamb = +25°C, IREF = 150µA, CS = 1µF Value Characteristic Output voltage Slope resistance (see note 1) Turn-on (knee) current Recommended operating current range Temperature coefficient (see note 2) RMS noise voltage Turn on time Turn off time Turn on time Turn off time Symbol Min.
