Maximum dropout is 0.35V at full load, so a 2.85V input rail leaves enough headroom for regulation across temperature and load steps. ## PSRR and noise rejection across frequency PSRR measures 60dB at 100Hz, rolling off to 50dB at 10kHz — the regulator attenuates low-frequency ripple from a switching pre-regulator or AC line hum by a factor of 1000 at the lower end. Above 10kHz the rejection continues to drop; for sensitive analog front-ends, a post-filter cap at the output helps maintain clean rails at switching frequencies above 100kHz. ## Quiescent current and enable for battery duty The Enable pin lets a system controller shut down the output completely, dropping the load to near-zero when the rail is not needed. ## Temperature grade and protection Built-in over-current, over-temperature, and short-circuit protection allow the regulator to survive output faults without external clamp diodes. Supplied in SC-74A / SOT-753 (SOT-23-5) surface-mount package, the footprint is standard for 5-pin SOT-23 with 0.95mm pitch — no special layout beyond a 1µF ceramic input cap and 1µF output cap placed close to the pins.","metaTitle":"LP5951MF-2.5/NOPB LDO 2.5V 150mA SOT-23-5","metaDescription":"Texas Instruments LP5951MF-2.5/NOPB linear regulator, fixed 2.5V output, 150mA, 55µA Iq, SOT-23-5.
