Product Summary
The LM4040C20IDBZR of shunt voltage references is versatile, easy-to-use references that cater to a vast array of applications. 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 ensure a stable output voltage over a wide range of operating currents and temperatures. The LM4040C20IDBZR uses fuse and Zener-zap reverse breakdown voltage trim during wafer sort to offer four output voltage tolerances, ranging from 0.1% (max) for the A grade to 1% (max) 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 45 mA (typ), the LM4040C20IDBZR also is ideal for portable applications. The LM4040C20IDBZRxI is characterized for operation over an ambient temperature range of –40℃ to 85℃. The LM4040C20IDBZRxQ is characterized for operation over an ambient temperature range of –40℃ to 125℃.
