VMMC1 LDO Regulator
The VMMC1 LDO regulator is a programmable linear voltage converter that powers the multimedia card
(MMC) slot. It includes a discharge resistor and overcurrent protection (short-circuit). This LDO regulator
can also be turned off automatically when MMC card extraction is detected. The VMMC1 LDO can be
powered through an independent supply other than the battery; for example, a charge pump. In this case,
the input from the VMMC1 LDO can be higher than the battery voltage. Table 4-8 describes the regulator
characteristics.
