Key Features
- Precision 5.0 V shunt reference with ±1% initial accuracy (4.95 V to 5.05 V) for stable ADC and DAC bias in automotive systems
- Two-terminal shunt configuration requires only a series resistor—no additional bypass or startup circuitry—simplifying BOM and layout
- AEC-Q100 automotive-grade qualification ensures reliability across -40°C to 125°C for under-hood and body-electronics designs
- Micropower supply current enables use in always-on power domains and battery-backed standby circuits with minimal quiescent drain
- 3-pin SOT-23 package occupies less than 5 mm² PCB area, fitting the tightest space-constrained automotive and industrial PCBs
Applications
The LM4050QCEM3X5.0/NOPB is used as a precision 5 V bias reference for ADC reference inputs, DAC supply rails, and comparator threshold networks in automotive body electronics, infotainment systems, and industrial sensor interfaces. Its two-terminal shunt topology makes it a drop-in reference in resistor-biased circuits where no dedicated reference pin is available. AEC-Q100 qualification and 15-year YTEOL make it a reliable long-term supply choice for automotive tier-1 production programs.

Frequently Asked Questions
What output voltage accuracy does the LM4050QCEM3X5.0/NOPB guarantee over its rated temperature range?
The LM4050QCEM3X5.0/NOPB guarantees an output voltage between 4.95 V and 5.05 V, corresponding to ±1% initial accuracy at room temperature. Over the -40°C to 125°C automotive temperature range, the precision micropower design maintains tight regulation, making it suitable as a 5 V reference for 12-bit and 10-bit ADCs in automotive sensor acquisition chains.
How does the two-terminal shunt configuration of the LM4050QCEM3X5.0/NOPB simplify circuit design?
As a two-terminal shunt reference, the LM4050QCEM3X5.0/NOPB connects in parallel with the load, requiring only a series current-setting resistor to establish the operating point. This eliminates the input, output, and enable pins of a series reference IC, reducing the component count to 2 parts and simplifying PCB routing in space-constrained 3.3 V or 5 V battery-backed reference circuits.
Which automotive certification does the LM4050QCEM3X5.0/NOPB carry, and for what temperature range?
The LM4050QCEM3X5.0/NOPB is AEC-Q100 qualified, the standard stress-test qualification for automotive integrated circuits. It is rated for operation from -40°C to 125°C, covering under-hood, body electronics, and telematics applications where temperature cycling, humidity, and long-term reliability requirements exceed those of standard commercial-grade components.
For how many years is the LM4050QCEM3X5.0/NOPB expected to remain in production?
The LM4050QCEM3X5.0/NOPB carries a YTEOL (Years to End of Life) rating of 15 years, indicating Texas Instruments intends to manufacture the device for at least 15 more years. This long production horizon is critical for automotive OEM and tier-1 programs with 10–15 year vehicle model life cycles that require uninterrupted supply of qualified components without costly redesigns.
