LM4040CEX3-3.3+T

电压参考分流 -固定, 3.3V参考, ± 20ppm/°C, SC-70-3

The is an improved precision micropower shunt voltage reference in 3 pin SC-70 package. This two terminal shunt mode band gap voltage reference is ideal for space critical applications. The laser trimmed resistors ensure precise initial accuracy of 0.5% with ±20ppm/°C temperature coefficient IR = 10mA. The LM4040C has 45µA minimum shunt operating current capability with low dynamic impedance which ensures stable reverse breakdown voltage accuracy over a wide range of operating temperatures and currents. This device does not require an external stabilizing capacitor while ensuring stability with any capacitive load.
