The LM4040 is a precision two-terminal shunt mode,

bandgap voltage reference available in fixed reverse

breakdown voltages of 2.048V, 2.500V, 3.000V, 3.3V,

4.096V, and 5.000V. Ideal for space-critical applica-

tions, the LM4040 is offered in the subminiature 3-pin

SC70 surface-mount package (1.8mm

smaller than comparable devices in SOT23 surface-

mount packages (SOT23 versions are also available).

Laser-trimmed resistors ensure precise initial accuracy.

With a 100ppm/°C temperature coefficient, the device

is offered in four grades of initial accuracy ranging from

0.1% to 1%. The LM4040 has a 60µA to 15mA shunt

current capability with low dynamic impedance, ensur-

ing stable reverse breakdown voltage accuracy over a

wide range of operating temperatures and currents.

The LM4040 does not require an external stabilizing

capacitor while ensuring stability with any capacitive

load.

The LM4040 is guaranteed over the temperature range

of -40°C to +125°C.

For a 1.225V output version, refer to the LM4041 data

sheet.
