具有低噪声LDO和有出色瞬态响应的DC/DC转换器包含BOM，原理图及光绘文件

描述

This reference design features both a low noise LDO and a DC/DC convertor where both can source of to 3A of output current. The DC/DC design has focused on keeping transient response within 5%, a requirement when powering core voltages of digital loads. The LDO output also has good (...)
