Simple analogic volt regulator 5V 1A, it can be used on your vehicle to charge your smartphone (caution: power dissipation > 10W) When the output level tends to reduce, the voltage supplied from the tension divider reduce to, so the current drainned from the base of the passing element (transistor series with the load) is reducted, increasing the voltage level at the output of the circuit Circuito simples regulador de tensão de 14.4 volts para 5V com 1A de saída. pode ser usado para carregar o telefone no carro. (cuidado, dissipação de potência maior que 10W) Quando o nível de tensão da saída tende a reduzir, a tensão de referência do divisor também tende a reduzir fazendo com que o transistor de baixo drene menos corrente da base do elemento de passagem (transistor em série com a carga) desta forma aumentando o nível de tensão da saída.

I like this circuit, and while higher gain transistors work best, standard transistors aren't too bad either.
