Providing stable voltage to VRAM or secondary logic controllers.
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
Used to set the output voltage via a resistor divider or to enable/disable the chip. 4. Typical Application Circuit Up0104s Datasheet
Typically supports up to 5.5V or 6V, making it ideal for 3.3V and 5V rails.
Designed for low power consumption during standby. Providing stable voltage to VRAM or secondary logic
While you should always consult the official manufacturer PDF for precise tolerances, the UP0104s generally boasts the following technical profile:
Most variants are rated for 500mA to 1A , depending on the specific package and thermal dissipation. Key Specifications and Features Used to set the
The UP0104s is a popular Low-Dropout (LDO) linear regulator known for its simplicity and reliability in consumer electronics. Below is a detailed breakdown of its specifications, pinout, and application use cases. 1. Overview of the UP0104s
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.
