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 and 5.0V. The devices are available in 0.2% B-grade,

0.5% C-grade and 1% D-grade initial tolerances.

LM4040 F (SOT23)

Cathode

They are available in small outline SOT23 and SC70-5

surface mount packages which are ideal for applications

where space is at a premium.

Anode

Excellent performance is maintained over the 60µA to

15mA operating current range with a typical temperature

coefficient of only 20ppm/°C. The device has been

designed to be highly tolerant of capacitive loads so

maintaining excellent stability.
