LDO regulator is a kind of widely used power management chip in the mobile portable electric devices. A linear regulator with two LDO is designed with the output voltage of 2.8V and 3.0V. The circuit is simulated by means of Casence Hspice software, and the result shows that the designed LDO has the advantages of low power consumption, ultra low dropout, high output accuracy, high power supply rejection ratio and so on.
