Figure 52. LDO Architecture Diagram
8.3.3.1 No-Load Stability
The LDOs remain stable and in regulation with no external load. This is an important consideration in some
circuits, for example, CMOS RAM keep-alive applications.
8.3.4 Li-Ion Linear Charger
8.3.4.1 Charger Architecture
The LP3910 can safely charge and maintain a single cell Li-ion or Li-polymer battery operating from a regulated
6-V car adapter, AC wall adapter, or USB power (VBUS). Input power source selection of USB/adapter is
seamless. If present, the charger uses the adapter power regardless of the presence of USB power. The
connection of either power source is detected by the LP3910 device.
