Frequently Asked Questions
What are the input and output voltage specifications of the MCP1804T-C002I/DB?
The MCP1804T-C002I/DB accepts an input voltage from 14 V to 28 V with an absolute maximum of 30 V and provides a fixed 12.0 V regulated output. The typical dropout voltage is 0.65 V with a maximum of 0.85 V, enabling efficient regulation even when input-output differential is small. Maximum output current is 150 mA.
Which automotive or industrial circuits can use the MCP1804T-C002I/DB as the primary power regulator?
Automotive infotainment modules, industrial sensor interfaces, and embedded control boards operating from a 24 V bus can all use this device. The 12.0 V fixed output at up to 150 mA satisfies the rail requirement for numerous microcontrollers, CAN transceivers, and relay drivers, while the 28 V input rating covers standard 24 V industrial supply fluctuations without additional protection circuitry.
How does the SOT-223-3 package help with thermal management?
The SOT-223-3 package includes a large exposed metal tab that can be soldered directly to the PCB copper pour, reducing junction-to-ambient thermal resistance significantly compared to SOT-23 packages. This allows the MCP1804T-C002I/DB to sustain its 150 mA output rating at elevated ambient temperatures common in automotive engine bays or industrial enclosures operating up to 125°C.
Is MCP1804T-C002I/DB RoHS compliant and what is its lead-free status?
Yes, the MCP1804T-C002I/DB carries a Pb-free code of Yes, confirming it meets RoHS requirements and is manufactured without lead solder. This makes it suitable for consumer, automotive, and industrial products that must comply with European Union WEEE and RoHS directives, or for any design targeting 150 mA regulated 12 V rails in compliant end products.
