(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 in some cases causes symptoms of system-level instability such as ringing or oscillation, especially in the presence of load transients. If needed use a larger input capacitance, depending on the characteristics of the input voltage source.
(3) Effective output capacitance of 0.47μF minimum and 40μF maximum is required for stability. The effective output capacitance accounts for tolerance, temperature, voltage, and any other factors that affect the value, and is often 50% smaller than the capacitors specified value.
