(1) All voltages are with respect to GND.
(2) An input capacitor is not required for LDO stability. However, an input capacitor with an effective value of 0.47μF minimum is recommended to counteract the effect of source resistance and inductance, which may in some cases cause symptoms of system-level instability such as ringing or oscillation, especially in the presence of load transients. Using an input capacitor at least equal to the output capacitor is generally good practice.
(3) To help achieve fast settling and avoid instability, the output capacitance (including tolerance, bias voltage, temperature variations, etc.) should fall within the specified range.
