For an LDO rated at 50 mA output, this is a solid mid-range figure — enough to clean up a 5 V bus feeding a 4 V analog supply or a sensor bias rail without requiring a post-filter LC stage. The low Iq keeps the regulator efficient in always-on or battery-backed domains where every microamp counts. ## Dropout voltage and thermal envelope Maximum dropout voltage is 0.22 V at 50 mA. The SOT-23-5 package has a junction-to-ambient thermal resistance that limits dissipation. On-chip protection includes over-current, over-temperature, and short-circuit shutdown. An Enable pin allows the regulator to be gated by a logic-level signal — useful for sequencing or power-saving sleep modes.","metaTitle":"Texas Instruments LP2980AIM5X-4.0/NOPB LDO Regulator, 50 mA","metaDescription":"Texas Instruments LP2980AIM5X-4.0/NOPB is a 50 mA fixed-output LDO in SOT-23-5.
