LM338 Datasheet

The LM138/LM238/LM338 are adjustable 3-terminal positive voltage regulators capable of supplying in excess of 5A over a 1.2V to 32V output range. They are exceptionally easy to use and require only 2 resistors to set the output voltage. Careful circuit design has resulted in outstanding load and line regulation comparable to many commercial power supplies. The LM138 family is supplied in a standard 3-lead transistor package.

    i need help sir, i need to design asimple 6v to 12v dc converter that has simple componets which are avilable on market, because in uganda most componets are rare on the market so proporse for me on circuit. the other question is what does the L1 simble represent

    Veramente interessante.
    Di solito non mi fido degli schemi elettrici pubblicati sul web.
    Questa volta mi devo ricredere.
    Ho montato il caricabatteria seguendo le istruzioni, e funziona tutto molto bene.
    LM338k è un imntegrato eccezzionale.
    Grazie per aver pubblicato questi schemi.
