Thank you Ray,
Is this a good fit for 7805DT? https://www.mouser.com/ProductDetail/Texas-Instruments/LM7805MPX-NOPB?qs=sGAEpiMZZMuKfYsiLTIqmOvaw0XsyTvNqqLvRA46LNU%3d
and the MC34063 https://www.mouser.com/ProductDetail/Texas-Instruments/MC34063ADR?qs=sGAEpiMZZMuo%252bmZx5g6tFDMH32vPgmRI
… in fact, how do I find all the components quickly?
