LM4132CMF-3.0

Voltage Reference Overview

The LM4132CMF-3.0 is a precision series voltage reference manufactured by Texas Instruments, housed in a SOT-23-5 package. It provides a fixed output voltage of 3 V with an initial accuracy of ±0.2%. The device operates within a temperature range of -40°C to +125°C and features a maximum supply current of 60 µA (100 µA max). It supports a maximum load current of 20 mA and functions with an input voltage range from VREF + 400 mV up to 5.5 V.

Voltage Reference Feature Summary

• Utilizes EEPROM registers for curvature correction and package-level programming to maintain high accuracy.
• Includes an enable pin that facilitates a low-power shutdown mode.
• Capable of delivering up to 20 mA without requiring an output capacitor or buffer amplifier.

Voltage Reference Applications

• Instrumentation and process control systems
• Data acquisition systems
• Portable battery-powered equipment
• Precision regulators

Voltage Reference Procurement Notes

Verify the specific grade suffix 'C' corresponds to the required ±0.2% initial accuracy specification. Confirm the 'MF' suffix indicates the SOT-23-5 package type. Ensure the '-3.0' designation matches the target 3 V output requirement. Check RoHS compliance status if environmental regulations apply to the design.

Voltage Reference Selection Notes

Select this component when a compact surface-mount solution is needed for space-critical designs. The CMOS architecture offers cost-effectiveness compared to laser-trimmed bipolar references. Consider the 60 µA quiescent current for battery life optimization. Verify that the 20 mA drive capability meets the downstream circuit requirements.

Voltage Reference Part Context

This part belongs to the LM4132 family of precision voltage references. The family includes various grades (A through E) offering different accuracy levels and temperature coefficients. Other variants provide different fixed output voltages ranging from 1.8 V to 4.096 V. The LM4132-Q1 variant is available for automotive applications.

Voltage Reference Replacement Considerations

LM4132DMF-3.0/NOPB: Offers higher initial accuracy (±0.4%). LM4132EMF-3.0/NOPB: Provides lower initial accuracy (±0.5%). LM4132AMF-3.0/NOPB: Delivers superior initial accuracy (±0.05%) and lower temperature coefficient.
