Notes:
6. Dropout voltage is defined as the input to output differential voltage at which the output voltage drops 1% below the
nominal value measured at VIN = 5V.
7. Measured within 10Hz to 10kHz bandwidth.
8. Measured at DC, specified at 120 Hz.
9. CIN = 22µF, COUT = 10µF. Both capacitors are low ESR X7R type.
