For a 5V rail, that means the input must stay above 6V to maintain regulation under light load — a 7.5V or 9V unregulated supply is a typical match. At full 500 mA load, expect the dropout to rise; the datasheet curve shows the trade-off. ## Protection set — over-temp, reverse polarity, short circuit Built-in protection features include over-temperature shutdown, reverse polarity protection, and short-circuit current limiting. These reduce the need for external clamp diodes or foldback circuits on the 5V rail, simplifying the BOM for industrial or automotive-grade designs.","metaTitle":"Texas Instruments LM2937ET-5.0/NOPB LDO Regulator, 5V Fixed","metaDescription":"Texas Instruments LM2937ET-5.0/NOPB is a 5V fixed-output LDO voltage regulator rated for 500 mA.
