I am trying to Identify this SMD component, Pin 1 GND , 2-VCC, 3-? Out I can identify top letter is C , Bottom is G11, I think it might be a transistor but it odd being connected to the main power rail. Part is from bremshey bike monitor. Unfortunately other identification is blocked out because it's burned out.
I agree. no idea,
but if one of the junctions isn't shorted determine if it PNP or NPN with a DMM then choose a 1W transistor that makes sense for V*I
You can always use a bigger part not SMD with higher Vceo.
e.g. linked to switch Motor in regenerator mode 80V? then 100mA, low V switch? then 30V 500mA
e.g. NPN 2SD1463 , PNP 2SB1045 (100V 50mA)
At least it is not an LDO like U7.
What event triggered the failure?
I figured it out, It turned out to be an LDO 5.0V the way I solved it was I replaced it with a 3.3. LDO and it worked but the display was very dim. I figured the next one up would be a 5V regulator, so I desoldered one from another PCB put it on and it works like a charm. Thanks for your comments.
