Up0104s - Datasheet

Designed for low power consumption during standby.

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. Summary Table Typical Value LDO Linear Regulator Max Input Current Output Package SOT-223 / SOP-8 Efficiency High (for Linear)

Used to set the output voltage via a resistor divider or to enable/disable the chip. 4. Typical Application Circuit Up0104s Datasheet

Providing stable voltage to VRAM or secondary logic controllers.

The UP0104s is most commonly found in the or SOP-8 package. While the exact pin mapping can vary slightly between "fixed" and "adjustable" versions, the standard layout usually follows this logic: VIN (Input): The unregulated power supply input. GND (Ground): The common reference point for the circuit. VOUT (Output): The regulated, steady voltage output. Designed for low power consumption during standby

Typically supports up to 5.5V or 6V, making it ideal for 3.3V and 5V rails.

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 Summary Table Typical Value LDO Linear Regulator Max

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

In the world of power management and circuit design, choosing the right voltage regulator is often the difference between a stable device and one prone to unexpected resets. If you are looking for the information, you are likely dealing with a high-efficiency power delivery circuit.
