Control and protection — what the Enable and Power Good save you
The Enable pin lets you sequence the rail — pull it low to shut down the output without banging the input. Power Good gives an open-drain flag that goes high when the output is within regulation, handy for reset sequencing on an FPGA or SoC. Soft Start limits inrush current on the output cap, which matters when the load has a large decoupling bank. Protection includes Over Current, Over Temperature, Short Circuit, and UVLO — the UVLO threshold is set internally, so the part stays off until the input is high enough to keep dropout in spec.
The 115 µA quiescent current (1.5 mA max supply current) keeps the self-heating low in standby, but at 1.5A output the power dissipation in the package is the real thermal limit — the exposed pad needs a good thermal connection to a copper plane.
