Quiescent current is 25 µA typical, and the maximum supply current is 425 µA — the low Iq suits battery-powered or always-on nodes where the regulator's own draw must not dominate the sleep budget. ## PSRR across the audio band and beyond Power-supply rejection ratio is 90 dB at 100 Hz, rolling to 60 dB at 100 kHz — this means the LDO attenuates low-frequency ripple (e.g., 50/60 Hz mains hum and its harmonics) by a factor of ~31,600, while higher-frequency switching noise from a buck converter upstream sees only ~1,000× rejection. For a 3.1 V rail feeding an audio codec or precision ADC, the 90 dB PSRR at 100 Hz keeps supply-borne artifacts below the noise floor of a 16-bit system; the roll-off above 10 kHz means the input filter ahead of the LDO should handle switching frequencies above 100 kHz. ## Package and temperature grade for board integration Protection features include over-temperature shutdown and short-circuit current limiting — the LDO folds back output current during a fault and recovers once the junction cools, preventing thermal runaway in a sustained overload. RoHS3 compliant per the manufacturer's declaration — no restricted substances above the threshold; the part carries the /NOPB suffix indicating lead-free (Pb-free) construction.","metaTitle":"LP5907SNX-3.1/NOPB LDO, 3.1V Fixed, 250mA, 4-X2SON","metaDescription":"Texas Instruments LP5907SNX-3.1/NOPB LDO, 3.1V fixed output, 250mA, 90dB PSRR at 100Hz.
