MAXIM INTEGRATED / ANALOG DEVICES LM4040DEX333T Voltage Reference

The LM4040DEX3-3.3+T is a precision micropower shunt voltage reference in a 3-pin SC-70 package. This two-terminal, band gap voltage reference is ideal for space-critical applications. It features laser-trimmed resistors for an initial accuracy of 1% and a temperature coefficient of ±20 ppm/°C at 10mA load current. The device offers a minimum shunt operating current of 45 µA, low dynamic impedance, and stable reverse breakdown voltage across a wide temperature range. It does not require an external capacitor for stability and provides a fixed 3.3V output voltage. Suitable for power management, consumer electronics, portable devices, and industrial applications.
