The maximum input voltage is the shunt regulation voltage, which is typically 5.5 V and can range from 5.3 V to 6.0 V over the specified temperature range.

Guaranteed by design for thermal shutdown. When the thermal junction temperature of the ADP1621 reaches approximately 150°C, the ADP1621 goes into thermal

shutdown and the GATE voltage is pulled low. When the junction temperature drops below about 140°C, the soft start sequence is initiated and the ADP1621 resumes

normal operation.
