The timing waveforms for the TC1301B RESET output
are shown in Figure 5-4. Note that the RESET
threshold input for the TC1301B is V
to RESET threshold detector connection is made
internal in the case of the TC1301B.

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
exceeding approximately 150

operation. If the internal power dissipation continues to
be excessive, the device will again shut off. The V
and RESET circuit will continue to operate normally
during an overtemperature fault condition for both the
TC1301A and TC1301B.
