LM4030BMF-2.5/NOPB

Overview

The LM4030BMF-2.5/NOPB is a micropower shunt voltage reference from Texas Instruments, offering an output of 2.5 V with ±0.1% initial accuracy and a temperature coefficient of 75 ppm/°C. It operates within a supply voltage range up to 6 V and supports a maximum shunt current of 20 mA. The device functions across an extended temperature range from -40°C to +125°C and is housed in a compact SOT-23-5 surface-mount package.

Feature Summary

• Provides stable reference voltage via shunt topology
• Ensures high precision with tight initial accuracy tolerance
• Operates efficiently at low power consumption levels

Applications

• Portable battery-powered instrumentation
• Data acquisition systems requiring precise references
• Handheld meters and test equipment

Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free compliance and RoHS adherence as per manufacturer specifications. Confirm the 'B' grade designation matches the required ±0.1% accuracy for your application. Ensure the SOT-23-5 footprint aligns with your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a fixed 2.5 V reference is needed with tighter accuracy than standard series references. The shunt configuration requires a series resistor to limit current. Consider the 75 ppm/°C drift if operating in environments with significant thermal fluctuations compared to lower drift alternatives.

Part Context

This part belongs to the LM4030 family of micropower shunt voltage references designed for space-constrained applications. It serves as a precision alternative to Zener diodes, offering superior temperature stability and lower noise characteristics suitable for sensitive analog signal conditioning circuits.

Replacement Considerations

LM4030AIMF-2.5/NOPB offers improved ±0.05% accuracy. LM4030DMF-2.5/NOPB provides ±0.2% accuracy. Verify pinout compatibility and thermal performance when substituting within the same package type.
