LM4040 PRECISION MICROPOWER SHUNT VOLTAGE REFERENCES Description Pin Assignments
The LM4040 is a family of bandgap circuits designed to achieve precision micro-power voltage references of 2.5V, 3.0V, 3.3V, 4.096V,
(Top View)
and 5.0V. The devices are available in 0.2% B-grade, 0.5% C-grade, and 1% D-grade initial tolerances. They are available in smal outline SOT23 surface mount packages, which are 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 * Pin 3 must be left floating or connected to pin 2 loads, which maintains excellent stability.
