LM4132DMF-2.5

Voltage Reference Overview

The LM4132DMF-2.5 is a precision low-dropout voltage reference from Texas Instruments, housed in a SOT-23-5 package. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±0.4%. The device operates within a junction 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 up to 5.5 V.

Voltage Reference Feature Summary

• Features an enable pin that allows for a low-power shutdown mode.
• Utilizes CMOS band-gap architecture with EEPROM registers for high precision.
• 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

Voltage Reference Procurement Notes

Verify the specific grade suffix 'D' corresponds to the required ±0.4% initial accuracy and 20 ppm/°C temperature coefficient specifications. Confirm the SOT-23-5 package type matches the design footprint. Ensure the automotive qualification status aligns with project requirements if applicable.

Voltage Reference Selection Notes

Select this component when a compact SOT-23 form factor is necessary alongside a fixed 2.5 V reference. It is suitable for applications requiring moderate load currents up to 20 mA while maintaining space constraints. Consider the D-grade tolerance if tighter accuracy is not critical.

Voltage Reference Part Context

This part belongs to the LM4132 family of precision voltage references manufactured by Texas Instruments. The family includes various voltage options and grades (A through E) to accommodate different accuracy and cost requirements across industrial and automotive sectors.
