In the event of a faulted output load, the maximum
current the LDO output will permit to flow is limited
internally for each of the TC1301A/B outputs. The peak

If the internal power dissipation within the TC1301A/B
is excessive due to a faulted load or higher-than-
specified line voltage, an internal temperature-sensing
element will prevent the junction temperature from
