(1)
In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may
have to be derated. Maximum ambient temperature (TA(max)) is dependent on the maximum operating junction temperature (TJ(max)), the
maximum power dissipation of the device in the application (PD(max)), and the junction-to-ambient thermal resistance of the
part/package in the application (
θJA), as given by the following equation: TA(max) = TJ(max) – (θJA × PD(max)).
(2)
The minimum required supply voltage for startup is 2.05V. The part is functional down to the falling UVL (Under Voltage Lockout)
threshold
(3)
Shutdown current into VIN pin, includes internal leakage
(4)
VIN = VO + 1.0 V
(5)
The internal resistor divider network is disconnected from FB pin.
