    产品信息

    描述 Ideal for space-critical applications, the LM4040-N precision voltage reference is available in the sub-miniature SC70 and SOT-23 surface-mount package. The advanced design of the LM4040-N eliminates the need for an external stabilizing capacitor while ensuring stability with any capacitive load, thus making the LM4040-N easy to use. Further reducing design effort is the availability of several fixed reverse breakdown voltages: 2.048 V, 2.5 V, 3 V, 4.096 V, 5 V, 8.192 V, and 10 V. The minimum operating current increases from 60 µA for the 2.5-V LM4040-N to 100 µA for the 10-V LM4040-N. All versions have a maximum operating current of 15 mA.The LM4040-N uses a fuse and Zener-zap reverse breakdown voltage trim during wafer sort to ensure that the prime parts have an accuracy of better than ±0.1% (A grade) at 25°C. Bandgap reference temperature drift curvature correction and low dynamic impedance ensure stable reverse breakdown voltage accuracy over a wide range of operating temperatures and currents.Also available is the LM4041-N with two reverse breakdown voltage versions: adjustable and 1.2 V. See the LM4041-N data sheet (SNOS641).特性SOT-23 AEC Q-100 Grades 1 and 3 available Small Packages: SOT-23, TO-92, and SC70 No Output Capacitor Required Tolerates Capacitive Loads Fixed Reverse Breakdown Voltages of 2.048 V, 2.5 V, 3 V, 4.096 V, 5 V, 8.192 V, and 10 V Key Specifications (2.5-V LM4040-N) Output Voltage Tolerance (A Grade, 25°C): ±0.1% (Maximum) Low Output Noise (10 Hz to 10 kHz): 35 µVrms (Typical) Wide Operating Current Range: 60 µA to 15 mA Industrial Temperature Range: –40°C to 85°C Extended Temperature Range: –40°C to 125°C Low Temperature Coefficient: 100 ppm/°C (Maximum)
