What are the key features of MCP1826T-1202E/DC?
- Fixed 1.2 V output with 1 A continuous current for direct FPGA and DSP core voltage supply
- 0.25 V typical dropout voltage enabling efficient regulation from 1.5 V or 1.8 V LiPo-derived rails
- SOT-223-5 package with large thermal pad facilitating up to 1 A load without external heatsink on standard PCB copper
What is MCP1826T-1202E/DC used for?
MCP1826T-1202E/DC is commonly used to power FPGA core voltage rails and DSP supplies in embedded systems where a stable 1.2 V rail must be derived from a 3.3 V or 5 V bus. Its 0.25 V typical dropout allows continued regulation even when input rail droops to 1.45 V under transient conditions, improving supply robustness in battery-backed systems. The SOT-223-5 form factor balances thermal performance and PCB area efficiency in dense board layouts.

Frequently Asked Questions
Can MCP1826T-1202E/DC regulate a 1.2 V output from a 1.5 V LiPo-derived input without dropout?
Yes. MCP1826T-1202E/DC specifies 0.25 V typical dropout, meaning it can deliver 1.2 V output from an input as low as 1.45 V. A 1.5 V input provides 0.3 V of headroom above the typical dropout, sustaining full 1 A output current even as the Li-ion cell discharges toward its lower voltage limit.
How much heat does MCP1826T-1202E/DC dissipate at 1 A from a 3.3 V input, and does SOT-223 handle it?
At 1 A from 3.3 V to 1.2 V, power dissipation is 2.1 W. The SOT-223-5 package has a junction-to-case thermal resistance of approximately 10°C/W; with a 2 cm² copper pour on a standard 1.6 mm FR4 PCB, total thermal resistance to ambient is roughly 40°C/W, giving a junction temperature rise of about 84°C above ambient — within the absolute maximum rating when ambient is below 40°C.
Which embedded processor families benefit most from using MCP1826T-1202E/DC as a dedicated core supply?
Microcontrollers and FPGAs that require a 1.2 V core supply — such as many Xilinx Spartan-6 and Intel MAX 10 FPGA families, or ARM Cortex-A class processors — benefit from MCP1826T-1202E/DC's tightly regulated 1.2 V output with low noise. The 1 A current capacity covers most mid-range FPGA core currents (typically 200 mA to 800 mA at 1.2 V), and the fixed output eliminates resistor divider tolerance errors.
