The 95 µA quiescent current keeps standby drain low for battery-operated equipment that spends most of its time in sleep. ## Industrial temperature and protection suite The Enable pin lets a host MCU gate the output rail, and built-in over-current, over-temperature, and short-circuit protection cover the common fault modes without external supervisory circuitry. The control and protection features reduce external component count, simplifying layout and BOM. The NOPB suffix confirms lead-free construction; no special handling beyond standard MSL is required.","metaTitle":"Texas Instruments LP2985AIM5X-3.1/NOPB LDO, 3.1V, 150mA","metaDescription":"Texas Instruments LP2985AIM5X-3.1/NOPB fixed-output LDO: 3.1V, 150mA, 45dB PSRR at 1kHz, SOT-23-5.
