PRODUCTION DATA.
The LDO responds quickly to a transient (large-signal response) on the input supply (line transient) or the output current (load transient) resulting from the LDO high-input impedance and low output-impedance across frequency. This same capability also means that the LDO has a high power-supply rejection ratio (PSRR) and, when coupled with a low internal noise-floor (Vn), the LDO approximates an ideal power supply in ac (small-signal) and large-signal conditions.
The choice of external component values optimizes the small- and large-signal response. The NR/SS capacitor (CNR/SS) and feed-forward capacitor (CFF) easily reduce the device noise floor and improve PSRR.
