Up0104s Datasheet May 2026

Managing power for Wi-Fi modules and processors.

Usually features a dropout as low as 400mV at full load.

Includes built-in thermal shutdown and current limiting to prevent the chip from burning out during a short circuit. 3. Pin Configuration (Pinout) Up0104s Datasheet

Implementing the UP0104s is straightforward. To ensure stability, the datasheet typically recommends:

If you are repairing a device and see a small 3-pin or 8-pin chip marked with "UP0104," "uP0104," or "0104s," you have found your regulator. In many cases, failure of this chip results in the device failing to "power on" or exhibiting "no display" symptoms on a GPU, as the logic chips aren't receiving their required voltage.

A 1µF to 10µF ceramic capacitor placed close to the VIN pin to filter out line noise.

It is frequently found on motherboards, graphics cards (GPUs), and networking equipment where it steps down voltage for sensitive logic components. 2. Key Specifications and Features In many cases, failure of this chip results

Providing stable voltage to VRAM or secondary logic controllers.
