LM4128BMF-3.0/NOPB

Voltage Reference Overview

The LM4128BMF-3.0/NOPB is a precision series voltage reference from Texas Instruments, housed in a SOT-23-5 surface-mount package. It provides a fixed output voltage of 3 V with an initial accuracy of ±0.2%. The device features a temperature coefficient of 75 ppm/°C and supports a maximum shunt current of 20 mA. It operates within an input voltage range up to 6 V and functions reliably across a temperature range of -40°C to +125°C.

Voltage Reference Feature Summary

Delivers high-precision fixed voltage output with tight initial accuracy tolerance.
Optimized for low power consumption suitable for battery-powered applications.
Designed for stable performance over wide industrial temperature ranges.

Voltage Reference Applications

Portable instrumentation requiring precise voltage references
Battery-operated measurement systems
Data acquisition channels

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS standards. Confirm the 'BMF' designation aligns with the required accuracy grade and temperature coefficient specifications. Ensure the SOT-23-5 footprint matches the target PCB layout constraints before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when a 3 V reference with ±0.2% initial accuracy is required. Consider the 75 ppm/°C temperature coefficient for thermal stability needs. Verify that the 20 mA maximum shunt current meets the load requirements and that the 6 V maximum input voltage accommodates the supply rail variations.

Voltage Reference Part Context

This part belongs to the LM4128 family of micropower series voltage references. It shares the same functional architecture as other variants in the series but is specifically configured for a 3 V output. The family is characterized by low noise and high precision, making it suitable for demanding analog signal processing tasks.
