Up0104s Datasheet May 2026

Used to set the output voltage via a resistor divider or to enable/disable the chip. 4. Typical Application Circuit

Managing power for Wi-Fi modules and processors. Up0104s Datasheet

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

A 10µF (or larger) low-ESR capacitor is essential for the LDO's stability loop. Without this, the regulator may oscillate. 5. Common Use Cases
