 LM4040
LM4040
Improved Precision Micropower Shunt Voltage
Reference with Multiple Reverse Breakdown Voltages
General Description
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 applications,
the LM4040 is offered in the subminiature 3-pin SC70
surface-mount package (1.8mm x 1.8mm), 50% 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, ensuring
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.
