LM4040/LM4041

Precision Micropower Shunt Voltage

Reference

Features

General Description

 Small SOT-23 package

 No output capacitor required

 Tolerates capacitive loads

 Fixed reverse breakdown voltages of 1.225, 2.500V,

4.096V, and 5.000V

Ideal for space critical applications, the LM4040 and

LM4041 precision voltage references are available in the

subminiature (3mm × 1.3mm) SOT-23 surface-mount

package.

The LM4040 is available in fixed reverse breakdown

voltages of 2.500V, 4.096V, and 5.000V. The LM4041 is

available with a fixed 1.225V or an adjustable reverse

breakdown voltage.

 Adjustable reverse breakdown version

 Contact Micrel for parts with extended temperature

range.

The minimum operating current ranges from 60μA for the

LM4041-1.2 to 74μA for the LM4040-5.0. LM4040 versions

have a maximum operating current of 15mA. LM4041

versions have a maximum operating current of 12mA.

Applications

 Battery-powered equipment

 Data acquisition systems

 Instrumentation

 Process control

 Energy management

 Product testing

The LM4040 and LM4041 have bandgap reference

temperature drift curvature correction and low dynamic

impedance, ensuring stable reverse breakdown voltage

accuracy over a wide range of operating temperatures and

currents.

 Automotive electronics

 Precision audio components
