I bought electronic components but I have doubts. Part Number TC1015-1.8VCT713 with A59S marking and TK71638SIL with L3B marking.

It's good? Thanks

If that marking is indeed L3B (and not L38) then it's more like an LP5951MF-1.8 LDO. Whereas the marking A59S seems to suggest rather the TC1014 part from Microchip.

  • \$\begingroup\$ Agree with you, I was thinking of TC1014-3.3VCT713 and for the other it' possible for LP5951MF-1.8 LDO. \$\endgroup\$ Commented Sep 28, 2023 at 11:09
  • \$\begingroup\$ I checked for L3B and finally I think LP5951MG-1.8 \$\endgroup\$ Commented Sep 28, 2023 at 15:04
  • \$\begingroup\$ LP5951MG is a SC-70 package whilst the LP5951MF is a SOT23. Well in any case I guess you got the right answer pretty much 95%. Feel free to indicate if this answered your question or if it was useful at least .. cheers ;-) \$\endgroup\$
