Abstract

reguladores de queda baixa (ldo) são descritos aqui para fornecer tensões reguladas para múltiplos domínios de tensão. em uma modalidade, um regulador de tensão compreende uma pluralidade de transistores de passagem, cada da pluralidade de transistores de passagem sendo acoplado entre um trilho de fornecimento de entrada e uma respectiva saída de uma pluralidade de saídas de regulador. o regulador de tensão também compreende uma pluralidade de resistores de mediação configurados para mediar uma pluralidade de tensões de realimentação para gerar uma tensão de realimentação média, em que cada da pluralidade de tensões de realimentação fornece realimentação de tensão para uma saída respectiva da pluralidade de saídas de reguladores. o regulador de tensão compreende ainda um amplificador tendo uma primeira entrada acoplada à tensão de realimentação média e uma segunda entrada acoplada a uma tensão de referência, em que o amplificador é configurado para acionar a pluralidade de transistores de passagem em uma direção que reduz uma diferença entre a tensão de referência e a tensão de realimentação média.
