Title: Unable to find this part using Google
Post by: bifferos on July 27, 2021, 11:25:48 am

I've tried:  "119xB17-33", "D119xB17-33" nothing.

Anyone know what they are?  I am hoping they are 3.3v regulators  ;D   I inherited them from someone with a load of other parts.

That looks like a AP1117 voltage regulator from Diodes Inc - https://www.diodes.com/assets/Datasheets/AP1117.pdf (https://www.diodes.com/assets/Datasheets/AP1117.pdf)

The DII is the logo.  "9x" is the date code - Year 9 (assume 2019), Week 50.  And "17-33" is for the 3.3v variety.
