Listed as Active and ROHS3 compliant. No last-time-buy risk — this regulator is current-production and available through independent distribution.
Fixed output — the regulator delivers a regulated 2.8V without external feedback resistors.
Yes, it includes both over-current and over-temperature protection features.
PSRR is 75 dB at 120 Hz, which provides strong rejection of line-frequency ripple for clean analog supplies.
