good eve all, im trying to find a components identity proper but all i have to go on is the code on the component. im hoping perhaps someone here may be familiar with the part in smt package. i believe its a regulator, the code on the package which is a sot-3 i believe, is BfZTD, also under the code are some dots and dashes, as follows ● --○○ not sure if that helps. ive tried some searches but no luck as of yet. the board its on runs from a single lipo cell 80mA. any direction would be appreciated at this point in discovering the identity of this device! cheers j
