In operation, the short-circuit protection produces current fold-back at the input due to the tracking con- verter. If the output is shorted, the linear regulator will limit the output current to IOM. The tracking converter will maintain a constant voltage drop of 0.8 V across the linear regulator. This condition results in typically 550 mW dissipation (IOM . 0.8 V). Short-circuit or thermal- shutdown activation will cause the OLF terminal, an open- drain diagnostic output flag, to go LOW.
