CAT8900 Precision Analog Voltage References The CAT8900 is a high precision voltage reference providing very accurate voltage regulation with low supply current consumption. CAT8900 is ideal for use in battery powered systems where operating current needs to be minimized and there can be a great variation in supply voltages. It will source or sink up to 10 mA of load current, and can for most applications, forgo the use of an output bypass capacitor. The device is supplied in a space saving three terminal SOT−23 package. http://onsemi.com Features SOT23−3 TP, TB SUFFIX CASE 527AG • Reference Voltages: • • • • • 1.024 V, 1.200 V, 1.250 V, 1.800 V, 2.048 V, 2.500 V, 2.600 V, 3.000 V, 3.300 V Low Supply Current: 450 nA (Typical) Initial Accuracy: Class A: ± 0.5 mV Class B: ± 1.0 mV Class C: ± 2.5 mV Class D: ± 5.0 mV Drift Performance: 20 ppm/°C SOT−23 3−Lead Package This Device is Pb−Free, Halogen Free/BFR Free, and RoHS Compliant MARKING DIAGRAM 3 S3YM 2 1 S3 = Specific Device Code Y = Production Year = (Last Digit) M = Production Month = (1 − 9, A, B, C) Typical Applications • • • • • PIN CONNECTIONS Battery Powered Systems A/D and D/A Converters Precision Regulator Systems Power Supplies Portable Medical Equipment 1 VIN 3 GND 2 VOUT VIN VIN C 0.1 mF VOUT VOUT (Top View) CAT8900 PIN FUNCTIONS GND Figure 1.
