Up0104s | Datasheet Free
The UP0104S is a high-performance 3A Low Dropout (LDO) linear regulator typically manufactured by uPI Semiconductor Corp (often listed via distributors like Veswin Electronics or Jotrin Electronics). It is designed for applications where high current delivery, low noise, and space efficiency are critical, such as in personal electronics and data center computing. Key Technical Specifications
d. Protection
- OCP: Detected via low-side RDS(on) sensing — no current sense resistor needed.
- OVP: Latches off if FB exceeds ~0.8V.
- Thermal shutdown (~150°C).
