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.
