LM4040/4041

Precision Micropower Shunt Voltage Reference

General Description

Features

Ideal for space critical applications, the LM4040 and LM4041

precision voltage references are available in the subminia-

ture (3mm × 1.3mm) SOT-23 surface-mount package.

• 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

• Adjustable reverse breakdown version

• Contact Micrel for parts with extended temperature

range.

The LM4040 is the 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 break-

down voltage.

The LM4040 and LM4041’s advanced design eliminates the

need for an external stabilizing capacitor while ensuring

stability with any capacitive load, making them easy to use.

Key Specifications

• Output voltage tolerance (A grade, 25°C) .. ±0.1% (max)

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.

• Low output noise (10Hz to 100Hz)

LM4040 ................................................ 35µV

LM4041 ................................................ 20µV

• Wide operating current range

LM4040 ................................................ 60µA to 15mA

LM4041 ................................................ 60µA to 12mA

• Industrial temperature range .................. –40°C to +85°C

• Low temperature coefficient ................100ppm/°C (max)

The LM4040 and LM4041 utilizes zener-zap reverse break-

down voltage trim during wafer sort to ensure that the prime

parts have an accuracy of better than ±0.1% (A grade) at

25°C. Bandgapreferencetemperaturedriftcurvaturecorrec-

tion and low dynamic impedance ensure stable reverse

breakdown voltage accuracy over a wide range of operating

temperatures and currents.
