Key Features
- Fixed 0.8 V output with 0.2 V typical dropout enables regulation from single-cell Li-ion down to near depletion
- 300 mA CMOS LDO with 2.1 V to 6 V input range suits FPGA core power, DSP logic, and sub-1 V digital subsystems
- 5-pin SOT-223 package with exposed pad provides superior thermal performance for continuous 300 mA operation in compact designs
Applications
The MCP1824T-0802E/DC powers sub-1 V core supply rails in FPGAs, DSPs, and low-power application processors where digital logic requires a regulated 0.8 V domain distinct from I/O and analog supplies. Portable computing and embedded AI inference devices use its 300 mA capability and 0.2 V dropout to efficiently derive the core rail from a 3.3 V or 5 V system bus. Industrial sensor hubs and programmable logic controllers employ the SOT-223 package's thermal pad to maintain stable 0.8 V regulation across the full industrial temperature range under continuous current load.

Frequently Asked Questions
Why is a 0.8 V output LDO such as MCP1824T-0802E/DC needed for modern FPGA designs rather than using the 1.8 V rail?
Modern mid-range FPGAs such as Intel Cyclone 10 and Lattice ECP5 require dedicated 0.8 V to 1.0 V core supply rails separate from 1.8 V or 3.3 V I/O banks. Using the MCP1824T-0802E/DC provides a fixed 0.8 V, 300 mA regulated core supply with only 0.2 V dropout, ensuring clean regulation even when the upstream 3.3 V rail dips, and avoiding the complexity of a full buck converter for moderate core current loads.
What is the dropout voltage of MCP1824T-0802E/DC, and how does that affect operation from a 1.5 V AA battery supply?
The MCP1824T-0802E/DC has a typical dropout voltage of 0.2 V and a maximum of 0.32 V at 300 mA load. From a fresh 1.5 V AA alkaline input, the regulator maintains a stable 0.8 V output until the battery discharges to approximately 1.1 V, extracting significantly more battery capacity than a device with a 0.5 V or higher dropout would allow under the same 300 mA continuous load condition.
How does the SOT-223-5 package of MCP1824T-0802E/DC help manage thermal dissipation at maximum load?
At 300 mA with a 5 V input and 0.8 V output, the MCP1824T-0802E/DC dissipates up to (5 V − 0.8 V) × 0.3 A = 1.26 W. The 5-pin SOT-223 package exposes a large thermal tab that, when soldered to a copper ground plane on the PCB, reduces junction-to-ambient thermal resistance to approximately 30 °C/W, keeping junction temperature rise to about 38 °C above ambient at maximum load — well within the safe operating range.
