A Low Dropout Regulator with Low Quiescent Current [PDF]

Advances in Intelligent Systems Research, 2015
This paper introduces a low dropout regulator (LDO) by bipolar process. This LDO is composed of a starting circuit, a bandgap reference, an amplifier and power transistors. The bandgap produced a reference voltage about -1.25V, this voltage will be amplified to -5V by the error amplifier, power transistors and feedback resistances, and the output of ...
