Description
The FAN2560 is a linear low-dropout (LDO) regulator
with a split-supply architecture. Separate bias and
supply inputs allow bias to be taken directly from the
battery, while the input is taken from a lower pre-
regulated source. This allows a smaller differential
voltage between input and output, which provides
greater efficiency over a wider VBAT range.
The FAN2560 is available in a fixed-voltage output,
5-bump, WLCSP package.
