19-1704; Rev 5; 1/09 Improved Precision MicropowerShunt Voltage ReferenceLM4041General DescriptionFeatures The LM4041 is a precision two-terminal shunt mode, ♦ Ultra-Small 3-Pin SC70 Package bandgap voltage reference with a fixed reverse break- ♦ 0.1% (max) Initial Accuracy down voltage of 1.225V. Ideal for space-critical appli- cations, the LM4041 is offered in the subminiature 3-pin ♦ 100ppm/°C (max) Temperature Coefficient SC70 surface-mount package (1.8mm ✕ 1.8mm), 50% Guaranteed over -40°C to +125°C Temperature smaller than comparable devices in SOT23 surface- Range mount packages (SOT23 versions are also available). ♦ Wide Operating Current Range: 60µA to 12mA Laser-trimmed resistors ensure precise initial accuracy. ♦ Low 20µVRMS Output Noise (10Hz to 10kHz) With a 100ppm/°C temperature coefficient, the device ♦ 1.225V Fixed Reverse Breakdown Voltage is offered in four grades of initial accuracy ranging from 0.1% to 1%. The LM4041 has a 60µA to 12mA shunt ♦ No Output Capacitors Required current capability with low dynamic impedance, ensur- ♦ Tolerates Capacitive Loads ing stable reverse-breakdown voltage accuracy over a wide range of operating temperatures and currents. Ordering Information The LM4041 does not require an external stabilizing PIN-TOP capacitor while ensuring stability with any capacitive PARTTEMP RANGEPACKAGEMARK load.
