Frequently Asked Questions
What input voltage range does the MCP1804T-C002I/OT support, and can it handle automotive battery transients?
The MCP1804T-C002I/OT accepts input voltages from 14V to 28V with a 30V absolute maximum, providing margin to absorb load dump transients common in 12V and 24V automotive or industrial bus environments. This wide tolerance helps protect downstream 12V circuits from voltage spikes without requiring additional clamping components.
How much current can the MCP1804T-C002I/OT continuously supply to a 12V load?
The MCP1804T-C002I/OT delivers up to 150mA continuously at its fixed 12V output, with a typical dropout voltage of 0.65V. This current level is sufficient for powering sensors, relay coils, analog amplifiers, and other medium-current 12V loads in industrial and automotive board designs.
When would a designer choose the MCP1804T-C002I/OT over a switching regulator for a 12V rail?
In applications where noise sensitivity and component count are priorities, the MCP1804T-C002I/OT's linear topology eliminates switching noise that can corrupt analog measurements or RF signals. For loads under 150mA with input voltages close to 14V, the 0.65V typical dropout means power dissipation stays below 100mW, making the LDO thermally practical without a heatsink.
