Part Details:

LM4041 March 2005 Precision LM4041Precision Micropower Shunt Voltage ReferenceGeneral Description Key Specifications (LM4041-1.2) Ideal for space critical applications, the LM4041 precision j Output voltage tolerance Micropower voltage reference is available in the sub-miniature SC70 and (A grade, 25°C) ±0.1%(max) SOT-23 surface-mount packages. The LM4041 s advanceddesign eliminates the need for an external stabilizing capaci- j Low output noise tor while ensuring stability with any capacitive load, thus (10 Hz to 10kHz) 20µVrms making the LM4041 easy to use. Further reducing design j Wide operating current range 60µA to 12mA effort is the availability of a fixed (1.225V) and adjustable j Industrial temperature range -40°C to +85°C reverse breakdown voltage. The minimum operating currentis 60 µA for the LM4041-1.2 and the LM4041-ADJ. Both j Extended temperature range -40°C to +125°C versions have a maximum operating current of 12 mA. j Low temperature coefficient 100 ppm/°C (max) Shunt The LM4041 utilizes fuse and zener-zap reverse breakdownor reference voltage trim during wafer sort to ensure that theprime parts have an accuracy of better than ±0.1% Applications (A grade) at 25°C.
