FAN1539/FAN1540 Rev. 1.1.1

Electrical Characteristics—FAN1540D18X

Unless otherwise speciﬁed, VIN = 3.135V to 3.465V, Tj = 25°C, IMAX = 1.3A. Boldface limits apply over operating

junction temperature range of 0°C

≤ TJ ≤ 125°C.

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 = 3.3V.

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.
