The main application specifications and models of LDOs in mobile phones.
What is LDO
LDO, or Low Dropout Regulator, is a low-dropout linear regulator that uses a transistor or field-effect transistor (FET) operating in its saturation region to subtract excess voltage from the input voltage of the application to produce a regulated output voltage.
Application specifications and models of LDO in mobile phones.
Although the mobile phone platform manufacturer's own PMU has integrated dozens of LDOs, these integrated LDOs are mainly used to supply power to the functions of various functional modules of the system.
1.Power the **dd of the camera, use 18v or 28v ldo
The **DD current of the camera is not large, the average current is generally less than 100mA, and most mobile phone customers use 300mA LDO to power supply, and the main ** merchants and models are as follows:
2.Power the ***d of the camera, 105v/1.1v
**D Peak current At present, some camera sensors are close to 1A, and the average current is about 200mA, and customers use 1A or 12a/1.5A output voltage adjustable LDO for power supply.
3.Application of multi-channel LDOs.
Now mobile phones are equipped with multiple cameras, some high-end mobile phones have 4 cameras in the rear, 2 cameras in the front, each camera must have the aforementioned **DD and ***D two power supplies, some high-end cameras with AF and OIS also need voice coil motor VCM power supply, OIS optical image stabilization sensor power supply, and some Japanese camera sensors also need io power supply voltage. The following is the power supply of 2 different camera modules from a mobile phone manufacturer.
