Set cap. close to PMIC
For EOS
Set cap. and shortpad close to PMIC
Set cap. close to PMIC
1. "Typical Cap" defined in design notice is the minimum cap. to LDO Cout.
2. NC cap can move to application, if (PCB L<20nH, PCB R<0.2 ohm)
=> value and placement of Cap, please refer design notice
Note 21-1:
Schematic design notice of "21_POWER_MT6357_LDO"
If these power trace can meet LDO layout constraint, these CAP can be NC or removed.
Please refer to MT6357 design notice.
Note 21-2:
Output cap range please follow MT6357CRV LDO design notice
Note 21-3:
Ext. buck option
w/ EXT VS2 Buck w/o EXT VS2 Buck
C801 10uF 22uF
Ext Buck BOM option
1.46V
Note: 21-4
Note 21-4: Please set R803 and R803 close to C826, making star connection among VIO18_PMU, AVDD18_SOC, and
EMI_VDD1 near to LDO cap. C826
Please also refer to MT6357 design notice for further detail design information
Note 21-5: Please connect VS2_LDO1(F15) to VS1_PMU if voltage applied to VCAMD(E17) >= 1.3 V
