Delivering a fixed 2.5 V output at up to 150 mA, it fits low-power digital and analog rails that need a clean, regulated supply without external resistor dividers. ## PSRR and dropout — what they mean for your rail With 45 dB of PSRR at 1 kHz, this LDO knocks down switching ripple from a buck converter by a factor of about 180 — enough to keep a sensitive ADC reference or audio codec supply clean, though higher-frequency noise above 100 kHz will pass through more readily. Maximum dropout is 0.58 V at full load, so the input rail must stay above 3.08 V to maintain regulation at 150 mA — a typical 3.3 V rail with 0.2 V of ripple still holds margin. Quiescent current is 95 µA typical, making it reasonable for always-on peripherals in battery gear, though not the lowest-Iq option for microamp-level sleep modes. ## Industrial temp range and protection set Built-in over-current, over-temperature, and short-circuit protection mean the part shuts down gracefully rather than letting smoke out if a downstream fault occurs — useful in field-replaceable modules where the load is not always predictable. ## SOT-23-5 — field-swap friendly Surface-mount footprint is standard; the pinout is unambiguous with the enable pin on pin 5, making orientation checks quick under a loupe. ## Sourcing and compliance ROHS3 compliant, so it ships into RoHS-regulated markets without exemption paperwork.","metaTitle":"Texas Instruments LP2985IM5-2.5/NOPB LDO, 150mA, 2.5V","metaDescription":"Active Texas Instruments LP2985IM5-2.5/NOPB LDO regulator, 150 mA fixed 2.5 V output, 45 dB PSRR, -40°C to 125°C.
