Frequently Asked Questions

How wide of an input voltage range can the LM76003RNPR handle in variable-supply systems?

The LM76003RNPR accepts input voltages from a minimum of 3.5 V up to a maximum of 60 V, with a nominal rating of 24 V, making it suitable for automotive and industrial rails that fluctuate well beyond standard 12 V or 24 V bus levels.

When was the LM76003RNPR introduced, and what long-term availability can buyers expect?

Introduced by Texas Instruments in 2017, the LM76003RNPR carries a projected years-to-end-of-life rating of 15 years while retaining its full 60 V maximum input voltage specification, giving buyers confidence in long-term availability for industrial and automotive designs with extended production lifespans.

Why would an adjustable step-down regulator like the LM76003RNPR suit multi-rail industrial designs?

With an adjustable output range spanning 1 V to 57 V and current-mode control combined with pulse frequency modulation, the LM76003RNPR can be configured to generate multiple precise voltage rails from a single 60 V-rated input supply.
