Frequently Asked Questions
Can MCP1826S-1202 power a 1 A FPGA core supply from a standard 3.3 V rail with adequate dropout margin?
Yes. MCP1826S-1202 provides 1 A output at 1.2 V from input voltages as low as 2.3 V. From a 3.3 V input rail, the headroom is 3.3 V minus 1.2 V equals 2.1 V, which far exceeds the 400 mV maximum dropout requirement, ensuring stable regulation at full 1 A load for FPGA core and logic supply rails.
What thermal considerations apply when using MCP1826S-1202 in a 1 A continuous-load application?
At 1 A output with a 3.3 V input, the MCP1826S-1202 dissipates approximately 2.1 W of power. The DDPAK-3 package provides a large exposed pad for heat sinking, but a PCB copper area or external heatsink is recommended to keep junction temperature below the maximum rating, especially in elevated ambient temperature industrial environments.
For compliance-sensitive industrial designs, what certifications does MCP1826S-1202E/EB carry?
MCP1826S-1202E/EB is RoHS-compliant and lead-free (Pb-free code Yes), meeting EU RoHS Directive requirements for restricted hazardous substances. The extended temperature range variant (E suffix) supports operation beyond the standard commercial 0°C to 85°C range, making it suitable for industrial equipment requiring operation to -40°C.
