PRECISION MICROPOWER SHUNT VOLTAGE REFERENCE PRELIMINARY INFORMATION TCN4040 TCN4040 PRECISION MICROPOWER SHUNT VOLTAGE REFERENCE Features s s s s s s s Small Packages … SOT-23B-3, TO-92, and SO-8 Output Capacitor Not Required Handles Capacitive Loads Fixed Reverse Breakdown Voltage of 2.5V Low Output Noise Wide Operating Current Range (60µA to 15mA) – 40°C to + 85°C Operating Temperature Range GENERAL Description For applications in tight quarters, the TCN4040 precision voltage reference is available in a space-saving 3mm x 1.3mm SOT-23B-3 surface mount package. The TCN4040 eliminates the need for an external stabilizing capacitor while maintaining stability with any capacitive load. The minimum operating current is 60µA. The maximum operating current is 15mA. To ensure that the prime parts have an accuracy of better than ±0.5% (C grade) at 25°C, the TCN4040 uses fuse and zener-zap reverse breakdown voltage trim during wafer sort. Low dynamic impedance and bandgap reference temperature drift curvature correction maintain stable reverse breakdown voltage accuracy over a wide range of operating temperatures (– 40°C to + 85°C) and currents from (60µA to 15mA). The TCN4040 also is available in both adjustable and 1.2V versions.
