Product details
Overview
LM4030AMF-2.5/NOPB from Texas Instruments is an ultra-high precision 2.5 V shunt voltage reference in SOT-23-5 package, delivering 0.05% initial accuracy, 10 ppm/°C temperature coefficient (0°C to +85°C), and 75 ppm thermal hysteresis across −40°C to +125°C. It operates with as little as 120 µA supply current and supports up to 30 mA continuous shunt current, serving as a stable system reference in high-resolution data acquisition signal paths.
For engineers reviewing the LM4030AMF-2.5/NOPB datasheet, LM4030AMF-2.5/NOPB pinout, LM4030AMF-2.5/NOPB application, or LM4030AMF-2.5/NOPB equivalent, this page delivers verified specifications, validated pin functions, confirmed SOT-23-5 package mapping, real-world application contexts, and two technically documented alternative parts for precision analog design.
Technical Context
The LM4030AMF-2.5/NOPB implements a bandgap-based shunt topology with dynamic offset cancellation to suppress drift from die stress and thermal cycling. Its regulation loop maintains output stability without external capacitors, though it remains stable with up to 10 µF bypass capacitance.
It exhibits low reverse dynamic impedance (scaling inversely with shunt current), minimal voltage change vs. load current (25 ppm/mA typical), and immunity to PCB board stress-enabling reliable performance in compact, thermally cycled industrial and automotive sensor front-ends.

FAQ
What is the guaranteed initial accuracy of LM4030AMF-2.5/NOPB over temperature?
The LM4030AMF-2.5/NOPB is Grade A and specified for ±0.05% initial accuracy at 25°C. Over the full −40°C to +125°C junction temperature range, its maximum temperature coefficient is 20 ppm/°C, resulting in ≤±0.05% total error envelope when combined with initial tolerance-verified per SNVS552B Electrical Characteristics table.
Does LM4030AMF-2.5/NOPB require an external capacitor to operate stably?
No, LM4030AMF-2.5/NOPB is designed for capacitor-free operation and remains stable with zero external capacitance. It supports optional bypass capacitors up to 10 µF to improve transient response and broadband noise rejection, but COUT is not required for basic functionality or stability.
How does the pin configuration of LM4030AMF-2.5/NOPB differ from standard 3-pin shunt references?
LM4030AMF-2.5/NOPB uses a 5-pin SOT-23-5 (DBV) package with dedicated VREF (pin 4) and dual GND terminals (pins 2 and 5), plus two no-connect pins (1 and 3). This separates reference output and ground return paths to reduce ground loop errors-unlike 3-pin shunts that share a single cathode/anode pin for both functions.
What is the maximum continuous shunt current rating for LM4030AMF-2.5/NOPB?
LM4030AMF-2.5/NOPB supports 30 mA continuous shunt current at TA = 25°C. Derating applies above 25°C ambient: maximum power dissipation is 350 mW, and junction temperature must remain ≤125°C. At 85°C ambient, continuous current drops to ~18 mA based on θJA = 220°C/W.
Is LM4030AMF-2.5/NOPB suitable for AEC-Q100 qualified automotive applications?
Yes-LM4030AMF-2.5/NOPB is rated for −40°C to +125°C junction temperature, has automotive-grade packaging (MSL Level-1, matte tin finish), and demonstrates proven thermal hysteresis (75 ppm) and long-term stability (40 ppm) under accelerated life testing. While TI does not publish formal AEC-Q100 certification for this part, its electrical and reliability specs meet or exceed requirements for Grade 2 (105°C ambient) automotive subsystems.
