The maximum dropout voltage is 1V at the full 1A load, meaning the input rail needs to stay above 11V to keep the output in regulation — a common margin for 12V vehicle or industrial supplies. Power supply rejection ratio is 63 dB at 120 Hz, which filters line ripple from a rectified AC source or a switching pre-regulator. ## Protection set and temperature range On-chip protection includes over current, over temperature, reverse polarity, and short circuit — these reduce the need for external clamp diodes or foldback circuits on a 10V rail. ## Active lifecycle, DDPAK package availability It is supplied in the DDPAK/TO-263-3 package, also known as TO-263-4 (3 leads plus tab). The tape-and-reel variant (SX suffix) is the standard ordering option for automated assembly; cut-tape quantities are also available through distribution. ## Sourcing and ordering posture","metaTitle":"LM2940SX-10/NOPB – TI 10V 1A LDO Regulator, TO-263, Active","metaDescription":"Texas Instruments LM2940SX-10/NOPB fixed 10V output, 1A LDO in DDPAK/TO-263-3. 63dB PSRR at 120Hz, 1V max dropout, -40°C to 125°C.
