(1) All voltages are with respect to GND.
(2) An input capacitor is required 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. A larger input capacitor may be necessary depending on the source impedance and system requirements.
(3) A BIAS input capacitor is not required for LDO stability. However, a capacitor with a derated value of at least 0.1 µF is recommended to maintain transient, PSRR, and noise performance.
