Built-in over-current, over-temperature, and short-circuit protection cover the common failure modes. An enable pin (active-high logic) lets the system shut down both outputs for sleep modes, dropping Iq to near zero.
RoHS non-compliant; if your BOM requires RoHS, factor in an exemption or look for a lead-free variant.
Yes — 5V is within the 7V maximum input rating and provides ample headroom above the 3.3V and 2.5V output rails.
