POWER SUPPLY REJECTION RATIO
PSRR
Based on an endpoint calculation using 1 mA and 500 mA loads. See Figure 6 for typical load regulation performance for loads less than 1 mA.
The adjust input function (ADJ) of the SENSE/ADJ pin applies to adjustable output voltage models only; whereas the sense function (SENSE) applies to fixed output
voltage models only.
3
Dropout voltage is defined as the input-to-output voltage differential when the input voltage is set to the nominal output voltage. This specification applies only for
output voltages greater than 3.0 V.
4
Start-up time is defined as the time between the rising edge of EN to VOUT being at 90% of its nominal value.
5
Current-limit threshold is defined as the current at which the output voltage falls to 90% of the specified typical value. For example, the current limit for a 5.0 V output
voltage is defined as the current that causes the output voltage to fall to 90% of 5.0 V, or 4.5 V.

Ensure that the minimum input and output capacitance is greater than 0.7 μF over the full range of operating conditions. The full range of operating conditions in the
application must be considered during device selection to ensure that the minimum capacitance specification is met. X7R and X5R type capacitors are recommended;
Y5V and Z5U capacitors are not recommended for use with any LDO regulator.
