50PPM/DEGREE PRECISION MICROPOWER SHUNT VOLTAGE REFERENCES WITH MULTIPLE REVERSE BREAKDOWN VOLTAGES

The LM4050AIM3-2.1 are precision two-terminal, shuntmode, band gap voltage references available in fixed reverse breakdown voltage of 2.048VIdeal for space-critical applications, the LM4050/LM4051 are offered in 50% smaller than comparable devices in SOT23 surface-mount package. Laser-trimmed resistors ensure excellent initial accuracy. With a 50ppm/°C temperature coefficient, these devices are offered in three grades of initial accuracy 0.1% The LM4050AIM3-2.1 have 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. LM4050AIM3-2.1 do not require an external stabilizing capacitor while ensuring stability with any capacitive loads. LM4050AIM3-2.1 specifications are guaranteed over the temperature range of -40°C to +125°C.
