Frequently Asked Questions
What is the maximum output current that MCP1804T-1802I/OT can supply continuously?
The MCP1804T-1802I/OT delivers up to 150 mA of continuous output current at a fixed 1.8 V, making it suitable for powering low-power microcontrollers, memory chips, and digital logic ICs without requiring external current-limiting components.
How wide is the input voltage range of MCP1804T-1802I/OT, and which supply rails is it compatible with?
The device accepts input voltages from 3.8 V to 28 V (absolute maximum 30 V), so it can be driven directly from 5 V, 12 V, or 24 V rails commonly used in industrial and automotive designs, providing flexible integration across multiple system architectures.
When would an engineer choose MCP1804T-1802I/OT over a switching regulator for a 1.8 V rail?
For applications where output ripple must stay below a few millivolts—such as sensitive analog front-ends or RF circuits operating from a 5 V or 12 V rail—the MCP1804T-1802I/OT is preferred because it is a linear regulator with a 2.7 V maximum dropout voltage and produces inherently clean DC output without switching noise.
Is MCP1804T-1802I/OT RoHS-compliant and lead-free?
Yes, the MCP1804T-1802I/OT is fully RoHS-compliant and lead-free (Pb-free code: Yes). The SOT-23-5 package uses a matte-tin finish, meeting the environmental requirements for consumer electronics and industrial equipment sold in the EU and globally.
