LM4040AEM3-3.0+T

LM4040AEM3-3.0+T is an improved precision micropower shunt voltage reference with multiple reverse breakdown voltages. Laser-trimmed resistors ensure precise initial accuracy. With a 100ppm/°C temperature coefficient. It 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. It does not require an external stabilizing capacitor while ensuring stability with any capacitive load. Applications include portable, battery-powered equipment, notebook computers, cell phones, and industrial process controls.
