The is a specialized power management integrated circuit (IC) manufactured by uPI Semiconductor (often rebranded or distributed by UIMICRO). It is primarily used as a linear voltage regulator in high-density electronic designs, such as motherboard power sections or video cards. Core Features & Specifications
The uP0104 series represents a robust solution for power regulation in consumer electronics. While newer LDOs offer lower dropout voltages and lower quiescent currents, the uP0104 remains a cost-effective and reliable choice for general-purpose voltage regulation where efficiency requirements are moderate. Up0104s Datasheet
A go-to choice for Arduino or ESP32 projects requiring a clean 3.3V rail from a 5V source. 6. Identifying the UP0104s on a PCB The is a specialized power management integrated circuit
