General 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.
