Frequently Asked Questions
What input voltage range can the MCP1804T-3002I/OT accept while maintaining a stable 3.0 V output?
The MCP1804T-3002I/OT accepts input voltages from 5 V to 28 V (absolute maximum 30 V) and regulates them down to a fixed 3.0 V output with up to 150 mA current. The 1.3 V typical dropout means the input needs to be at least 4.3 V for proper regulation, making it well suited for 12 V automotive or 24 V industrial supply rails.
How does the MCP1804T-3002I/OT fit into a compact IoT sensor design with limited board space?
Packaged in the tiny SOT-23-5 footprint (approximately 2.9 mm × 1.6 mm), the MCP1804T-3002I/OT requires only a few bypass capacitors to implement a complete 3.0 V LDO power stage, saving significant PCB area compared to larger packages. This makes it an efficient choice for IoT sensor nodes where board space is limited and up to 150 mA current capacity is sufficient.
Is the MCP1804T-3002I/OT a suitable replacement for a 3.3 V LDO in a 3.0 V microcontroller application?
Yes, if the target microcontroller or peripheral specifies a 3.0 V nominal supply, the MCP1804T-3002I/OT directly matches that requirement with its fixed 3.0 V output, avoiding the need to over-voltage a 3.3 V-rated device. The 150 mA output current headroom is adequate for most 8-bit or low-power 32-bit microcontrollers plus supporting peripherals.
