The 2-pin fixed-output device requires no external capacitors for operation and is stable with all capacitive loads. Additionally, the reference offers low dynamic impedance, low noise, and low temperature coefficient to maintain a stable output voltage over a wide range of operating currents and temperatures. The LM4040 uses fuse and Zener- zap reverse breakdown voltage trim during wafer sort to offer four output voltage tolerances, ranging from 0.1% (maximum) for the A grade to 1% (maximum) for the D grade. Thus, a great deal of flexibility is offered to designers in choosing the best cost-to-performance ratio for their applications. Packaged in space-saving SC-70 and SOT-23-3 packages and requiring a minimum current of 45μA (typical), the LM4040 also is ideal for portable applications. The LM4040xI is characterized for operation over an ambient temperature range of – 40°C to 85°C. The LM4040xQ is characterized for operation over an ambient temperature range of – 40°C to 125°C.
