Power-supply rejection ratio spans 85 dB at 100 Hz down to 40 dB at 100 kHz — the low-frequency attenuation is strong enough to clean up ripple from a switching pre-regulator, but above 10 kHz the PSRR drops off and external filtering may be needed. ## Package and board-fit for hand rework Housed in a 6-WDFN exposed-pad package (6-WSON, 2.2x2.5 mm), the LP5900SDX-2.7/NOPB is surface-mount only. The enable pin lets you shut down the output; quiescent current drops to near zero when pulled low. Protection includes over-temperature shutdown and short-circuit current limiting — the part folds back, not latches, so a transient short on the output won't require a power cycle. ## Active production and compliance Input voltage max is 5.5 V — the part is designed for low-voltage rails, not automotive load-dump survival.","metaTitle":"LP5900SDX-2.7/NOPB LDO, 2.7V fixed, 150mA, 6-WSON","metaDescription":"Texas Instruments LP5900SDX-2.7/NOPB LDO regulator, 2.7V fixed output, 150mA, 85dB PSRR at 100Hz.
