行動裝置的CMOS LDO穩壓器

CMOS LDO Regulators for Portable Devices

相較於標準的低壓差(LDO)穩壓器系列，攜帶式裝置用的低壓差穩壓器其輸出入電壓差更低，因此可達到超低耗電的電源電路架構。
ROHM攜帶式裝置用低壓差穩壓器透過CMOS製程，達到超低耗電與高精度的目標。另備有超低輸出入電壓的產品系列，最適合可攜式裝置(行動電話/數位隨身聽等)或攜帶式裝置(DSC/DVC)等使用。
此外，在封裝陣容上還備有WLCSP(晶圓級CSP)/ SSON4(1.6 x 1.2)等超小型封裝，由於其輸出入部分與外接電容可對應陶瓷電容，因此對縮小裝置的體積有所貢獻。
