2.8V fixed LDO — what the ratings mean for your rail
PSRR is 85 dB at 100 Hz, 40 dB at 100 kHz. 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.
