Frequently Asked Questions
What is the maximum input voltage the LM25011AQ1MY/NOPB can handle, and why does this matter for automotive designs?
The LM25011AQ1MY/NOPB accepts input voltages from 6 V up to 42 V, making it tolerant of automotive load-dump transients that can briefly spike a 12 V rail above 40 V. This headroom allows designers to avoid external clamping components, simplifying BOM and improving reliability in harsh vehicle environments with 34 characterized electrical specs.
How is the output voltage of LM25011AQ1MY/NOPB set, and what is the minimum achievable output?
Output voltage is set by an external resistor divider connected to the feedback pin. The minimum adjustable output is 2.51 V, which is the internal reference voltage of the device. A 2-resistor network allows the designer to program any output between 2.51 V and a value limited by the input rail, offering flexibility for powering 3.3 V, 5 V, or custom rails from a single regulator IC.
In which package does LM25011AQ1MY/NOPB come, and how does it compare to through-hole alternatives for board space?
The device uses a 10-pin MSOP surface-mount package, which occupies roughly 3 mm x 3 mm of PCB area — significantly smaller than an equivalent DIP-8 through-hole package. This compact footprint suits high-density automotive ECUs and industrial modules where board real estate is limited, and the 2A rating eliminates the need for additional external pass transistors in most sub-2A load scenarios.
When would LM25011AQ1MY/NOPB be preferred over a fixed-output regulator in an automotive power tree?
When a design requires fine-tuned output voltages such as 2.8 V for sensor bias or 4.2 V for battery charging rather than standard 3.3 V or 5 V rails, an adjustable device like the LM25011AQ1MY/NOPB eliminates the need for multiple fixed regulators. Its AEC-Q100 automotive qualification and -40 °C to 125 °C operating temperature range mean it can serve diverse rail requirements across a vehicle platform with a single qualified part.
