Its PSRR starts at 90 dB at 100 Hz and rolls off to 60 dB at 100 kHz, which means it cleans up ripple from a switching regulator upstream — the 60 dB floor at 100 kHz still attenuates a 1 mV ripple to 1 µV at the output, keeping noise-sensitive analog rails clean. Maximum dropout is 250 mV at the full 250 mA load, so the input rail needs at least 3.55 V to maintain regulation. Quiescent current sits at 25 µA typical — low enough that in a battery-powered sensor waking once a minute, the regulator's own draw doesn't dominate the sleep budget. Operating temperature spans -40°C to 125°C, covering industrial enclosures and under-hood automotive ambient without derating. The SOT-23-5 package is small enough for tight layouts but still hand-solderable with a fine-tip iron — no hot-air station needed for a field swap. ## Active lifecycle — no LTB clock ticking Protection features include over-temperature shutdown and short-circuit current limiting — the output folds back under fault, then recovers automatically when the condition clears. No external protection diode needed for most loads under 250 mA.","metaTitle":"TI LP5907MFX-3.3/NOPB LDO, 250 mA, 3.3 V Fixed","metaDescription":"Texas Instruments LP5907MFX-3.3/NOPB linear regulator, 250 mA output, 3.3 V fixed, SOT-23-5.
