Bypass LDO
c
a To achieve specified accuracy, follow layout recommendations in QCC3031 QFN
Hardware Design Guide (80-CG380-1).
b Resistor value should be chosen such that the maximum fast charge current
corresponds to 100 mV of voltage drop.
C Varies linearly with the total current (in external) drawn by the Bypass LDO;
worst case inaccuracy is +3% corresponding to 50 mA Bypass LDO output.
