That 90 dB at low frequency means it attenuates 100 mV of 100 Hz ripple from an upstream switching regulator down to roughly 3 µV at the output — critical for powering analog sensor front-ends or the analog supply pin of a microcontroller where ripple couples into the ADC reference. The 25 µA quiescent current makes it viable for always-on circuits in automotive body controllers or keyless-entry modules where the regulator stays powered while the rest of the system sleeps. ## Dropout Voltage and Input Rail Budget Maximum dropout voltage is 0.25 V at 250 mA output. With a nominal 3.3 V supply, the headroom is only 50 mV — marginal; a 5 V rail or a 3.6 V pre-regulator gives comfortable margin. Output current is rated 250 mA continuous, with over-temperature and short-circuit protection built in. The single fixed output is 3.0 V, and the enable pin allows the regulator to be gated by a system power-good signal. ## Package and Footprint for Compact Layouts Housed in a SOT-23-5 package (SC-74A), the LP5907QMFX-3.0Q1 occupies roughly 3 mm × 3 mm of board area. The small footprint suits space-constrained ECUs or sensor modules where every square millimeter counts. Surface-mount assembly is standard reflow; no special handling beyond normal MSL precautions.","metaTitle":"LP5907QMFX-3.0Q1 LDO 3.0V 250mA AEC-Q100 SOT-23-5","metaDescription":"Texas Instruments LP5907QMFX-3.0Q1 LDO, 3.0V fixed output, 250mA, 90dB PSRR at 100Hz, AEC-Q100 qualified, -40°C to 125°C, active production.
