The protection set — over-current, over-temperature, short-circuit, and under-voltage lockout — is the standard complement for a modern LDO; UVLO prevents the output from coming up until the input rail is stable.
PSRR is 68 dB at 100 Hz, rolling off to 28 dB at 100 kHz. This means good rejection of low-frequency ripple (e.g., 100/120 Hz from a rectifier), but less attenuation above 10 kHz.
Yes, it is ROHS3 compliant.
