Using cat6219 conversion 3.3 V and directly use the 3.3 V battery conversion have what different, which one is better,

CodePudding user response:

CAT6219 SOT - 23 encapsulation, using 5 pin is 500 ma CMOS low dropout regulators, during the load current and line voltage changes provide quick response time
See you need to how much current load, different look at your design cost and appearance of the size of the difference,
As to which one is better, this is opinion
