Diodes Incorporated

AUTOMOTIVE GRADE 1.225V AND ADJUSTABLE PRECISION REFERENCE

Description

The LM4041 is a bandgap circuit designed to achieve a precision

micro-power voltage reference of 1.225 V; it is also available in an

adjustable version. The device is available in the small outline SOT23

surface mount package which is ideal for applications where space

saving is important.

The fixed output version is available in 0.5% C grade and 1% D grade

performance is maintained over the 60µA to 12mA 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 LM4041

voltage reference in both adjustable and 1.225V output variants for

automotive applications.

Automotive Grade supporting PPAPs.
