| description | The invention provides a low dropout linear regulator, a DC-DC power supply and a control method. The low dropout linear regulator comprises an analog power supply generation circuit and a power supply generation circuit. The analog power supply generating circuit is of an open loop structure and comprises a first power supply module, and the power supply generating circuit comprises a second power supply module. In the normal working mode, the driving current of the first power supply module is larger than the driving current of the first power supply module in the burst mode, in the normal working mode, the second power supply module is switched on, the power supply generating circuit outputs power voltage, and in the burst mode, the second power supply module is switched off. The static power consumption of the DC-DC power supply in the burst mode can be effectively reduced, and the reliability and the stability of the DC-DC power supply are effectively improved.
