LM4040Q数据手册集成电路（IC）的电压基准规格书PDF

描述 Description

The LM4040Q 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.

They 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 has been designed to be highly tolerant of capacitive loads therefore maintaining excellent stability.

This device offers a pin for pin compatible alternative to the industry standard LM4040 voltage reference for automotive applications.

The LM4040Q has been qualified to AEC-Q100 Grade 1 and is Automotive Grade supporting PPAPs.
