Product Overview

The LM4040DEM3-5.0+T is an improved precision micropower shunt voltage reference in 3 pin SOT-23 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 1% with ±30ppm/°C temperature coefficient (IR = 10mA). The LM4040D has 54µA 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.
  • Fixed reverse breakdown voltage of 5V
  • Operating temperature range from -40°C to 125°C
  • Low wideband output noise of 80µVrms (10Hz to 10KHz, IR=100µA)
  • Reverse breakdown voltage tolerance of ±50mV
  • Reverse dynamic impedance of 0.5ohm (IR = 1mA, f = 120Hz, IAC = 0.1IR)
