LM4040

LM4040 Precision micropower shunt voltage references Description The LM4040 is a family of bandgap circuits designed to achieve precision micro-power voltage references of 2.5V and 5.0V. The devices are available in 0.5% C-grade and 1% D-grade initial tolerances. They are available in small outline SOT23 surface mount package which is ideal for applications where space saving is important. 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. This device offers a pin for pin compatible alternative to the LM4040 voltage reference.
