LM4040CEM3-3.0+T

The LM4040CEM3-3.0+T is an improved precision micro power shunt voltage reference with multiple reverse breakdown voltages in 3 pin SOT-23 package. This precision two-terminal shunt mode, bandgap voltage reference available in fixed reverse breakdown voltages of 3V. 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%. 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.

• Low 45µVrms wideband noise at IR = 100µA, 10Hz ≤ f ≤ 10KHz
• Operating temperature range from -40°C to 125°C
• Tolerates capacitive loads
• Reverse breakdown voltage long-term stability is 120ppm at T = 1000h (3V)
• Maximum reverse dynamic impedance of 0.9ohm at IR = 1mA, f = 120Hz, IAC = 0.1IR
• Average reverse voltage temperature coefficient is ±100ppm/°C (max)
