AS3722 − Detailed Descriptions- Power Management Functions
Low Power LDO V2_5 Regulator
Description
The low power LDO V2_5 is needed to supply the chip core
(analog and digital) of the device. It is designed to get the
lowest possible power consumption, and still offering
reasonable regulation characteristics. The regulator has three
supply inputs selecting automatically the higher one. This gives
the possibility to supply the chip core either with the VBAT,
VSUP or VBAT_BKUP depending on the conditions. Bulk switch
comparators are used to avoid any parasitic current flow. To
ensure high PSRR and stability, a low-ESR ceramic capacitor of
min. 0.7μF must be connected to the output.
