elecTrical characTerisTics
less than the minimum endurance specification. The RESTORE_USER_ALL
command (NVM read) is valid over the entire operating temperature range.
Note 14: The LTC3883-1 quiescent current (IQ) equals the IQ of VIN plus
the IQ of EXTVCC.
Note 15: The LTC3883 includes overtemperature protection that is
intended to protect the device during momentary overload conditions.
Junction temperature will exceed 125°C when overtemperature protection
is active. Continuous operation above the specified maximum operating
junction temperature may impair device reliability.
