What are the key features of MCP1825T-5002E/DC?
- Fixed 5 V output voltage with tight regulation accuracy for stable logic and analog supply rails
- Low dropout voltage of only 0.21 V typical enabling operation from supplies as low as 5.21 V
- 500 mA output current capacity supporting microcontrollers, sensors, and peripheral loads
- SOT-223-5 package with exposed tab providing excellent thermal dissipation for higher power operation
- 6 V maximum input voltage range covering USB 5 V, lead-acid battery, and single-cell Li-Ion boosted supplies
What is MCP1825T-5002E/DC used for?
MCP1825T-5002E/DC is used in USB-powered device power trees, embedded systems requiring a clean 5 V rail from a 6 V or lightly loaded USB VBUS source, and industrial control modules where a 500 mA low-dropout regulator simplifies supply design. Its low dropout of 0.21 V makes it suitable for powering 5 V microcontrollers and analog sensors directly from a Li-Ion boost converter or regulated 5.5 V bus without excessive headroom requirements. The SOT-223-5 thermal pad also enables reliable continuous 500 mA operation on small PCBs with limited copper pour area.

Frequently Asked Questions
What is the dropout voltage of MCP1825T-5002E/DC, and how does it set the minimum usable input supply?
MCP1825T-5002E/DC has a typical dropout voltage of 0.21 V and a maximum of 0.35 V at 500 mA load. This means the input supply must be at least 5.35 V to guarantee a regulated 5 V output under worst-case conditions, enabling operation directly from a 5.5 V regulated bus or a Li-Ion boost converter output with minimal headroom requirements.
How much output current can MCP1825T-5002E/DC continuously supply, and what load scenarios does that cover?
MCP1825T-5002E/DC is rated for a continuous output current of 500 mA at 5 V. This is sufficient to power a 32-bit microcontroller drawing 50 mA, a Wi-Fi module drawing 200 mA peak, and several peripheral sensors totaling 100 mA simultaneously, with remaining headroom for transient load spikes in IoT gateway and industrial data acquisition designs.
What thermal advantage does the SOT-223-5 package of MCP1825T-5002E/DC offer over a SOT-23-5 regulator at 500 mA?
The SOT-223-5 package includes an exposed metal tab soldered to the PCB, giving a junction-to-board thermal resistance of approximately 20°C/W compared to over 100°C/W for a SOT-23-5 package. At 500 mA with a 1 V input-to-output differential, the SOT-223-5 dissipates 500 mW while keeping junction temperature only 10°C above board temperature, preventing thermal shutdown in designs operating at 85°C ambient.
In a USB bus-powered design, is MCP1825T-5002E/DC suitable as the primary 5 V regulator given typical USB VBUS tolerance?
USB VBUS is specified at 4.75 V to 5.25 V under load. Since MCP1825T-5002E/DC requires at least 5.21 V input for a 5 V regulated output with 0.21 V dropout, it may drop out of regulation when USB VBUS sags to 4.75 V under heavy load. It is best suited for use with a clean 5.5 V post-rectified supply or Li-Ion boost output rather than directly on USB VBUS if 500 mA regulated output is critical for system stability.
