The TPS51103 integrates three LDOs. The 5-V and 3.3-V LDOs are both rated at 100 mA and also include a glitch-free switch-over feature allowing for optimized battery life. An additional 3.3-V LDO is designed to provide an always on power output for the real time clock (RTC). The TPS51103 integrates a clock output to use with an external charge pump. The TPS51103 offers an innovative solution for optimizing the complex and multiple power rails typically found in a Notebook Computer. The TPS51103 is available in the 10-pin QFN package and is specified from –40°C to 85°C.
