AME AME4041 Shunt Bandgap Voltage Reference n General Description The AME4041 is a micropower 2-terminal band-gap voltage regulator diode. It operates over a 30µA to 20mA current range. Each circuit is trimmed at wafer sort to provide a ± 0.5% initial tolerance. The design of the AME4041 allows for a large range of load capacitances and operating currents. The low start-up current makes these parts ideal for battery applications. n Functional Block Diagram VR AME offers this part in a SOT-23 package.
