DESCRIPTION/ORDERING INFORMATION
The LM4040 series of shunt voltage references are 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
LM4040 uses fuse and Zener-zap reverse breakdown voltage trim during wafer sort to offer an output voltage
tolerance of 0.65%.
Packaged in a space-saving SOT-23-3 package and requiring a minimum current of 45 μA (typ), the LM4040
also is ideal for portable applications. The LM4040C25 is characterized for operation over an ambient
temperature range of –55°C to 125°C.
