Title: A novel low dropout regulator (ldo)
Inventor: CAO HUA
IPC: G05F1/46
Filed: 2019-01-11
Abstract: A novel low dropout regulator (LDO) is presented. Said LDO includes the generation of a first feedback signal and a second feedback signal. The first feedback signal and a reference signal connect to a first error amplifier. The second feedback signal and the first error amplifier output signal connect to a second error amplifier. The output signal from the second error amplifier is coupled to the gate of a Field-effect (FET) transistor. The FET transistor can be either a p-channel FET transistor, an n-channel FET transistor, a NMOS pass transistor, or a PMOS pass transistor. The positive input terminal or the negative input terminal of the first amplifier or of the second amplifier therefore need to be configured accordingly. When the source of the FET transistor is connected to the input voltage VIN, the drain of the FET transistor is the output voltage VOUT; when the drain of the FET transistor is connected to the input voltage VIN, the source of the FET transistor is the VOUT.
