According to the , the device is engineered for precision power management and signal integrity. Key technical parameters include: Package Type : Standard SOP-8 (8-pin Small Outline Package).
The SOP-8 package relies heavily on its ground pins and the underlying PCB copper trace geometry to shed heat. Ensure Pin 3 is connected to a wide copper pour or stitched to an inner ground plane using thermal vias to avoid triggering internal thermal shutdown mechanisms.
Often used to manage 5VDUAL voltage planes and sleep states (ACPI compliance). Up0104s Datasheet
The is a highly efficient Low Dropout (LDO) linear regulator controller manufactured by uPI Semiconductor Corp (and produced by suppliers like UIMICRO ). It is widely used across motherboard voltage regulation circuits, personal electronics, and automotive systems.
At its core, the UP0104S functions as a linear voltage regulator, creating a stable, lower voltage from a higher, potentially noisy input. Unlike the high-frequency switching of a PWM controller, a linear regulator operates by dissipating excess power as heat, making it suitable for moderate current demands where efficiency is not the primary concern. According to the , the device is engineered
Used in hybrid and electric powertrain systems.
Chosen by audiophiles and sound engineers to power portable audio amplifiers where power noise directly corrupts sound quality. Procurement and Cross-Referencing Ensure Pin 3 is connected to a wide
The uP0104S is engineered for applications requiring high precision and low noise, such as motherboard power stages or data acquisition boards.
