LM4040-N/LM4040Q-N Precision Micropower Shunt Voltage Reference

Check for Samples: LM4040-N, LM4040Q-N

FEATURES

DESCRIPTION

Ideal for space critical applications, the LM4040-N

•

2.5V/SOT-23 AEC Q-100 Grades 1 and 3

available

precision voltage reference is available in the sub-

miniature SC70 and SOT-23 surface-mount package.

The LM4040-N's advanced design eliminates the

need for an external stabilizing capacitor while

ensuring stability with any capacitive load, thus

making the LM4040-N easy to use. Further reducing

design effort is the availability of several fixed reverse

breakdown voltages: 2.048V, 2.500V, 3.000V,

4.096V, 5.000V, 8.192V, and 10.000V. The minimum

operating current increases from 60 μA for the 2.5-V

LM4040-N to 100 μA for the 10.0-V LM4040-N. All

versions have a maximum operating current of

15 mA.

•

Small Packages: SOT-23, TO-92 and SC70

No Output Capacitor Required

Tolerates Capacitive Loads

Fixed Reverse Breakdown Voltages of 2.048V,

2.500V,3.000V, 4.096V, 5.000V, 8.192V, and

10.000V

APPLICATIONS

•

Portable, Battery-Powered Equipment

Data Acquisition Systems

Instrumentation

The LM4040-N utilizes fuse and zener-zap reverse

breakdown voltage trim during wafer sort to ensure

that the prime parts have an accuracy of better than

±0.1% (A grade) at 25°C. Bandgap reference
