Notes:
(1) Vin max=30V
(2) Above 225°C (Tj), a minimum load current of few mA could be required.
(3) Max Power dissipation depends on packaging. CHT-LDOS in TO-3 or TO-254 packages presents a “junction-to-
case” thermal resistance of maximum 5°C/W (Rth).
(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
2.8+x/13 mA @ -30°C and 2.5+x/13 mA at 225°C.
(8) Defining “x” as the nominal voltage, the minimum power supply rejection ratio is …(tbd)….
