LM4041DYM3-1.2 TR Microchip

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