FAN1539/FAN1540 Rev. 1.1.1

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.
