The Texas Instruments LP5907MFX-3.3/NOPB is an ultra-low-noise 250 mA low-dropout regulator that delivers a fixed 3.3 V output in a compact X2SON package. With output noise of about 6.5 µVrms and high power-supply rejection, it is intended for RF, analog and other noise-sensitive rails where a clean, stable supply is essential.
