知识与技巧 027 LDO是如何工作的

>> YOUR LINK HERE: ___ http://youtube.com/watch?v=S5443DSweB8

本期视频将以LDO为例，来介绍线性稳压电路的特性，工作原理，以及在设计中应该注意的问题。 • 视频主要包含以下几部分的内容： • 直流电源稳压电路的分类 • 低压差稳压器（LDO）的基本要求和结构 • 低压差稳压器（LDO）工作状态分析 • 压差（Dropout Voltage）的计算和分析举例 • 线性稳压电路的应用限制 • 在下一个视频中，针对线性稳压电路的应用限制，将会介绍另一种更高效的直流稳压电路：开关稳压电路。","styleRuns":[{"startIndex":0,"length":63,"styleRunExtensions":{"styleRunColorMapExtension":{"colorMap":[{"key":"USER_INTERFACE_THEME_DARK","value":4294967295},{"key":"USER_INTERFACE_THEME_LIGHT","value":4279440147}]}},"fontFamilyName":"Roboto"},{"startIndex":63,"length":12,"styleRunExtensions":{"styleRunColorMapExtension":{"colorMap":[{"key":"USER_INTERFACE_THEME_DARK","value":4294967295},{"key":"USER_INTERFACE_THEME_LIGHT","value":4279440147}]}},"fontFamilyName":"Roboto"},{"startIndex":75,"length":20,"styleRunExtensions":{"styleRunColorMapExtension":{"colorMap":[{"key":"USER_INTERFACE_THEME_DARK","value":4294967295},{"key":"USER_INTERFACE_THEME_LIGHT","value":4279440147}]}},"fontFamilyName":"Roboto"},{"startIndex":95,"length":18,"styleRunExtensions":{"styleRunColorMapExtension":{"colorMap":[{"key":"USER_INTERFACE_THEME_DARK","value":4294967295},{"key":"USER_INTERFACE_THEME_LIGHT","value":4279440147}]}},"fontFamilyName":"Roboto"},{"startIndex":113,"length":28,"styleRunExtensions":{"styleRunColorMapExtension":{"colorMap":[{"key":"USER_INTERFACE_THEME_DARK","value":4294967295},{"key":"USER_INTERFACE_THEME_LIGHT","value":4279440147}]}},"fontFamilyName":"Roboto"},{"startIndex":141,"length":12,"styleRunExtensions":{"styleRunColorMapExtension":{"colorMap":[{"key":"USER_INTERFACE_THEME_DARK","value":4294967295},{"key":"USER_INTERFACE_THEME_LIGHT","value":4279440147}]}},"fontFamilyName":"Roboto"},{"startIndex":153,"length":48,"styleRunExtensions":{"styleRunColorMapExtension":{"colorMap":[{"key":"USER_INTERFACE_THEME_DARK","value":4294967295},{"key":"USER_INTERFACE_THEME_LIGHT","value":4279440147}]}},"fontFamilyName":"Roboto"}],"paragraphStyleRuns":[{"startIndex":63,"length":90,"listGroup":{"listType":"LIST_TYPE_BULLET","listItems":[{"listType":"LIST_TYPE_BULLET","startIndex":63,"length":12},{"listType":"LIST_TYPE_BULLET","startIndex":75,"length":20},{"listType":"LIST_TYPE_BULLET","startIndex":95,"length":18},{"listType":"LIST_TYPE_BULLET","startIndex":113,"length":28},{"listType":"LIST_TYPE_BULLET","startIndex":141,"length":12}]}},{"length":154}]},"headerRuns":[{"startIndex":0,"length":63,"headerMapping":"ATTRIBUTED_STRING_HEADER_MAPPING_UNSPECIFIED"},{"startIndex":63,"length":12,"headerMapping":"ATTRIBUTED_STRING_HEADER_MAPPING_UNSPECIFIED"},{"startIndex":75,"length":20,"headerMapping":"ATTRIBUTED_STRING_HEADER_MAPPING_UNSPECIFIED"},{"startIndex":95,"length":18,"headerMapping":"ATTRIBUTED_STRING_HEADER_MAPPING_UNSPECIFIED"},{"startIndex":113,"length":28,"headerMapping":"ATTRIBUTED_STRING_HEADER_MAPPING_UNSPECIFIED"},{"startIndex":141,"length":12,"headerMapping":"ATTRIBUTED_STRING_HEADER_MAPPING_UNSPECIFIED"},{"startIndex":153,"length":48,"headerMapping":"ATTRIBUTED_STRING_HEADER_MAPPING_UNSPECIFIED"}]}},{"itemSectionRenderer":{"contents":[{"continuationItemRenderer":{"trigger":"CONTINUATION_TRIGGER_ON_ITEM_SHOWN","continuationEndpoint":{"clickTrackingParams":"CK8BELsvGAIiEwjC_s3J5d-LAxXjcHoFHcg2O9Q=","commandMetadata":{"webCommandMetadata":{"sendPost":true,"apiUrl":"/youtubei/v1/next"}},"continuationCommand":{"token":"Eg0SC1M1NDQzRFN3ZUI4GAYyJSIRIgtTNTQ0M0RTd2VCODAAeAJCEGNvbW1lbnRzLXNlY3Rpb24%3D","request":"CONTINUATION_REQUEST_TYPE_WATCH_NEXT"}}}}],"trackingParams":"CK8BELsvGAIiEwjC_s3J5d-LAxXjcHoFHcg2O9Q=","sectionIdentifier":"comment-item-section","targetId":"comments-section"}}],"trackingParams":"CK4BELovIhMIwv7NyeXfiwMV43B6BR3INjvU"}},"secondaryResults":{"secondaryResults":{"results":[{"compactVideoRenderer":{"videoId":"sxQMK486EOE","thumbnail":{"thumbnails":[{"url":"https://i.ytimg.com/vi/sxQMK486EOE/hqdefault.jpg?sqp=-oaymwEbCKgBEF5IVfKriqkDDggBFQAAiEIYAXABwAEG
