LM4040Q

LM4040Q AUTOMOTIVE COMPLIANT PRECISION MICROPOWER SHUNT VOLTAGE REFERENCES Description The LM4040Q is a family of bandgap circuits designed to achieve precision micropower voltage references of 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V. The devices are available in 0.2% B-grade, 0.5% C-grade, and 1% D-grade initial tolerances. The devices are available in small outline, SOT23 surface mount package, which is ideal for applications where space is at a premium. Excellent performance is maintained over the 60µA to 15mA operating current range with a typical temperature coefficient of only 20ppm/°C. The device is designed to be highly tolerant of capacitive loads that maintain excellent stability. This device offers a pin-for-pin compatible alternative to the industry standard LM4040 voltage reference for automotive applications.
