I even called Maxim Integrated to verify my information that the top mark code matched their part number. I actually found this myself yesterday doing some research. Thank you for commenting and your assistence. I've been doing board repairs on electronics, mostly video game consoles for around 13 months now and am really interested in growing with this field. If anyone can lend their knowledge to a newbie I would appreciate it greatly. I have also attached a picture of the board area before removing the component as well as a picture I found during my web searches that supposedly shows what the pin values are with a good component. I have attached this picture for everyone's review along with a picture of the components before removal. I have plugged in the power supply to read the voltages of the system in standby mode and recorded the values I read on a picture I took of the pads without the component. I know there has to be a cleaner way to do it, hence the reason why I'm here. My web searches have found some people in Mexico had success in replacing this chip with a larger component, however this involves using jumper wires and mounting the component on the board by itself.

I would like to ask if someone can assist me in either identifying this component or sourcing a replacement that I can purchase from either Mouser or Digi-Key. There is another of these components near this one, I believe they may both be LDO chips that take 5v DC in and have the output voltage set by using resistors in circuit on one of the pins. I have been unable to source this component based off the case markings, which leads me to believe that the markings do not identify the item and may just be a lot code. I removed the component and the pad underneath pin 3 had lost it's continuity to ground. I tested continuity to ground on the pins for this little guy and discovered pins 2 and 3 had continuity to ground.

This component is an SMD component, package size SOT-23-5.

I discovered using a thermal camera that a certain component, labeled U5A1 on the board was heating up to over 125 degrees Celsius. I have an Xbox 360 S (Trinity model) that was missing numerous voltages on the motherboard. I recently discovered this forum and created my account today in the hopes that someone will be able to help me.
