What LD33 is
- LD1117AV33 - Low-dropout linear voltage regulator, 3.3V 800mA output. (SOT223 · on 1 of the parts below · in our catalogue with this marking)
One code, more than one part. SMD marking codes are short, and manufacturers reuse them: the same code can be a different part in a different package
(a SOT-23 transistor and a SOD-123 diode can both be marked LD33), or from a different maker. Check the package and what the part does in the circuit before replacing it.
