Quiescent current is 50 µA. ## Protection and package — what the bench tech sees Built-in over-temperature and short-circuit protection are standard for this class, but worth noting: if the output gets shorted to ground, the part limits current and shuts down thermally. The exposed pad on the 6-WSON needs a solid thermal via connection to the ground plane — without it, the 150 mA load at high ambient will hit the thermal limit faster than the datasheet curve suggests. ## Lifecycle and sourcing reality No last-time-buy notice, no EOL flag. ROHS3 compliant, so it passes the current EU restriction scope.","metaTitle":"LP5900SD-2.8/NOPB LDO Regulator, 2.8V Fixed Output, 150mA","metaDescription":"TI LP5900SD-2.8/NOPB is a 2.8V fixed-output LDO rated for 150mA.
