Description

The LM4040 is a precision two-terminal shunt mode, bandgap voltage reference available in fixed reverse breakdown voltages of 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V. Ideal for space-critical applications, the LM4040 is offered in the subminiature 3-pin SC70 surface-mount package (1.8mm x 1.8mm), 50% smaller than comparable devices in SOT23 surface-mount packages (SOT23 versions are also available).Laser-trimmed resistors ensure precise initial accuracy. With a 100ppm/°C temperature coefficient, the device is offered in four grades of initial accuracy ranging from 0.1% to 1%. The LM4040 has a 60µA to 15mA shunt current capability with low dynamic impedance, ensuring stable reverse breakdown voltage accuracy over a wide range of operating temperatures and currents.The LM4040 does not require an external stabilizing capacitor while ensuring stability with any capacitive load.The LM4040 is guaranteed over the temperature range of -40°C to +125°C.For a 1.225V output version, refer to the LM4041 data sheet.ApplicationsCell PhonesIndustrial Process ControlsNotebook ComputersPortable Battery-Powered Equipment
