ROHM’s regulator products can be sub-divided in numerous ways. Common categorization is by the device maximum output current rating (which is highly dependent on packaging), whether it is a fixed or variable output type, and whether there is a shutdown function included. Note that ROHM indicates the presence of a shutdown switch by inserting a “W” between the base part number and the package call-out. The CC0 Series is also a suitable substitute for ROHM’s legacy LDO regulators: BAxx series (fixed output/3-pin package), BAxxS series (fixed output with shutdown function/5-pin package), and BA00AS (variable output with shutdown function/5-pin package).
