Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under which operation of
the device is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the
Electrical Characteristics tables.
Note 2: All voltages are with respect to the potential at the GND pin.
Note 3: The Human body model is a 100 pF capacitor discharged through a 1.5 k
resistor into each pin. The machine model is a 200 pF capacitor discharged
directly into each pin. MIL-STD-883 3015.7
Note 4: Output voltage specification for the adjustable version includes tolerance of the external resistor divider.
Note 5: The input voltage range recommended for the specified output voltages are given below:
VIN = 2.5V to 5.5V for 0.7V ≤ VOUT < 1.875V
VIN =(VOUT +VDROP OUT) to 5.5V for 1.875 ≤ VOUT≤ 3.3V
Where VDROP OUT =ILOAD *(RDSON (P) +RINDUCTOR)
