Abstract

Patente de Invenção:<B>"REGULADOR DE VOLTAGEM DE DERIVAçãO QUE UTILIZA UMA VOLTAGEM DE REFERêNCIA FLUTUANTE"<D>. Trata-se de um regulador de voltagem de derivação que utiliza uma voltagem de referência que gera uma voltagem de saída flutuante com relação a uma voltagem a ser regulada. O regulador de voltagem de derivação da presente invenção também utiliza a voltagem a ser regulada como um suprimento de energia ao seu gerador de voltagem de referência, para os deslocadores de nível e para o amplificador operacional.
