Quiescent current is 2 mA typical, rising to 20 mA max under all load and temperature conditions. That Iq floor matters for always-on 5 V rails in battery-backed or low-standby designs where every milliamp on the input side counts. ## Protection set that reduces external BOM Over-temperature shutdown, reverse polarity protection, and short-circuit current limiting are integrated. In a 24 V truck or marine panel where reverse-battery events happen, the reverse polarity clamp saves a series diode — and the thermal shutdown handles a sustained overload without the regulator failing open or short. Short-circuit protection limits the output current during a fault rather than latching off, so the rail recovers automatically when the fault clears.","metaTitle":"LM2937ESX-5.0/NOPB 5V Fixed LDO Regulator, 500mA, DDPAK-3","metaDescription":"Texas Instruments LM2937ESX-5.0/NOPB is a 5V fixed-output LDO rated 500mA in DDPAK/TO-263-3.
