What are the key features of MCP1824ST-3002E/DB?
- Fixed 3.0V output with only 0.2V nominal dropout voltage for efficient low-headroom regulation
- 6V absolute maximum input rating accommodating Li-ion, USB, and regulated 5V supply rails
- SOT-223-3 package with exposed thermal pad for improved heat dissipation at higher load currents
- RoHS lead-free construction compliant with modern PCB assembly requirements
What is MCP1824ST-3002E/DB used for?
The MCP1824ST-3002E/DB powers 3.0V microcontrollers, wireless modules, and MEMS sensors in battery-operated IoT nodes where minimising dropout loss extends runtime from a single-cell Li-ion source. Its 0.2V nominal dropout enables reliable 3.0V output from a Li-ion cell that has discharged to as low as 3.2V, maximising usable battery capacity. Industrial sensor transmitters and portable instruments also use it to derive a clean 3.0V reference rail from a noisy 5V bus with minimal thermal dissipation.

Frequently Asked Questions
What dropout voltage does MCP1824ST-3002E/DB achieve and how does this benefit Li-ion battery designs?
The MCP1824ST-3002E/DB achieves a nominal 0.2V dropout voltage, allowing it to regulate 3.0V output from a Li-ion cell that has discharged to 3.2V, extracting more usable capacity before the system shuts down compared to regulators with 0.5V or higher dropout.
What input voltage range does MCP1824ST-3002E/DB accept and which supply rails does it suit?
It accepts input from 3.395V minimum up to 6V maximum with a 6.5V absolute maximum, making it compatible with single-cell Li-ion batteries, USB 5V rails, and regulated 5V DC supplies in embedded systems requiring a clean 3.0V output.
Why choose MCP1824ST-3002E/DB in SOT-223-3 over a smaller SOT-23 LDO for moderate load applications?
The SOT-223-3 package provides a larger thermal pad that dissipates more power than a SOT-23 body, enabling stable 3.0V regulation at higher load currents—typically up to 300 mA—without exceeding junction temperature limits in compact IoT and sensor module designs.
How does MCP1824ST-3002E/DB perform when powering an MCU that experiences rapid load transients?
The MCP1824ST incorporates internal output capacitor compensation and a fast transient response, maintaining 3.0V output within tight regulation bounds during sudden load steps from standby to active MCU modes, reducing the need for large bulk output capacitors on the PCB.
