Frequently Asked Questions
How much output current can MCP1826S-2502E/EB supply and what is its dropout voltage at full load?
The MCP1826S-2502E/EB delivers up to 1 A continuous output current with a typical dropout of 0.25 V and a maximum of 0.4 V, so it maintains a regulated 2.5 V output as long as the input stays above approximately 2.75 V to 2.9 V, depending on load.
Why is the DDPAK-3 package of MCP1826S-2502E/EB preferred for high-current 2.5 V supply designs?
The D2PAK (DDPAK-3) package features a large exposed copper tab that mounts flush to the PCB copper pour, providing a low thermal resistance path for the 1 A load current. This prevents excessive junction temperature rise compared to smaller SOT-23 or SOIC LDO packages at similar current levels.
Can MCP1826S-2502E/EB power an FPGA core or I/O bank directly from a 3.3 V supply?
Yes. With a 3.3 V input and a fixed 2.5 V output, MCP1826S-2502E/EB has an 0.8 V headroom — well above the 0.4 V maximum dropout — allowing it to supply FPGA I/O banks, DDR termination resistors, or other 2.5 V loads at up to 1 A without regulation loss.
What is the expected product availability horizon for MCP1826S-2502E/EB in long-lifecycle industrial designs?
The MCP1826S-2502E/EB carries a YTEOL of 9, indicating it is expected to remain in production for approximately 9 more years. This makes it a low lifecycle-risk choice for industrial and medical equipment designs that require component availability over multi-year production runs.
