(3) Max Power dissipation depends on packaging. CHT-LDOS in TO-3 or TO-254 packages presents a “junction-to-
(4) ppm are defined as [d(Vout)/d(T)]/Vout. For 5V mode, 40ppm corresponds to 200µV/°C.
(5) Defining “x” as the nominal voltage, the line regulation is better than x/5 mV/V.
(6) This includes the packaging parasitic resistor.
(7) Defining “x” as the nominal voltage, the typical quiescent current at 2V dropout can be approximated as
(8) Defining “x” as the nominal voltage, the minimum power supply rejection ratio is …(tbd)….
