What are the key features of UC385T-3G3?
- 5A continuous output current in a through-hole TO-220 package enables high-current 2.5V supply rails without external pass transistors
- 350mV typical dropout voltage at 5A full load preserves headroom efficiency when converting from 3.3V or 5V bus supplies
- Fixed 2.5V ±1% output accuracy meets tight core voltage tolerance requirements for FPGAs, DSPs, and memory power rails
What is UC385T-3G3 used for?
The UC385T-3G3 is designed for generating high-current 2.5V supply rails in industrial equipment, FPGA development boards, and embedded computing systems where 5A of regulated current is required from a 3.3V or 5V source. Its low 350mV dropout voltage minimizes power dissipation compared to standard LDOs at full current load, reducing heatsink requirements. The through-hole TO-220 package simplifies board assembly and supports external heatsinking for sustained high-current operation in demanding thermal environments.
