LM4040/LM4041 Precision Micropower Shunt Voltage Reference Features General Description
• Small SOT-23 Package Ideal for space critical applications, the LM4040 and • No Output Capacitor Required LM4041 precision voltage references are available in • Tolerates Capacitive Loads the subminiature SOT-23 surface-mount package. • Fixed Reverse-Breakdown Voltages of 1.225V, The LM4040 is available in fixed reverse-breakdown 2.500V, 4.096V, and 5.000V voltages of 2.500V, 4.096V, and 5.000V. The LM4041 • Adjustable Reverse-Breakdown Version is available with a fixed 1.225V or an adjustable reverse-breakdown voltage.
Applications
The minimum operating current ranges from 60 μA for • Battery-Powered Equipment the LM4041-1.2 to 74 μA for the LM4040-5.0. LM4040 • Data Acquisition Systems versions have a maximum operating current of 15 mA. • Instrumentation LM4041 versions have a maximum operating current of • Process Control 12 mA. • Energy Management The LM4040 and LM4041 have bandgap reference • Product Testing temperature drift curvature correction and low dynamic impedance, ensuring stable reverse-breakdown • Automotive Electronics voltage accuracy over a wide range of operating • Precision Audio Components temperatures and currents.
