Applications
The MCP1804T-5002I/OT is ideal for regulating 5 V rails in automotive sensor modules, industrial control boards, and battery-powered equipment operating from unregulated supplies up to 28 V. Its low dropout voltage of 1 V makes it effective in systems where the input rail closely tracks the output, extending battery run time. The SOT-23-5 package minimizes PCB footprint for space-constrained designs requiring a reliable, fixed-voltage supply.

Frequently Asked Questions
What is the input voltage range of the MCP1804T-5002I/OT, and can it be used directly from a 24 V industrial supply?
The MCP1804T-5002I/OT accepts input voltages from 7 V to 28 V, with an absolute maximum of 30 V, making it fully compatible with 24 V industrial supply rails. It delivers a stable 5.0 V output at up to 150 mA, suitable for powering microcontrollers, sensors, and communication modules on 24 V industrial control boards.
How does the MCP1804T-5002I/OT's 1 V typical dropout compare to similar SOT-23 LDOs when optimizing battery life?
With a typical dropout voltage of 1 V at 150 mA, the MCP1804T-5002I/OT requires the input to stay at least 6 V to maintain the 5.0 V output. Compared to older LDOs with 2 V or higher dropout, this 1 V specification allows operation from 6 V lithium packs or depleted alkaline batteries, extending usable runtime in portable equipment by reducing the dead-voltage margin.
Which thermal and layout considerations apply to the MCP1804T-5002I/OT in a 150 mA continuous-load design?
At full 150 mA output with a 28 V input and 5 V output, the MCP1804T-5002I/OT dissipates up to 3.45 W (23 V x 0.15 A), which exceeds the SOT-23-5 package thermal budget. Designers should derate the input voltage or reduce load current — for example, limiting input to 12 V yields only 1.05 W dissipation, well within the package's safe operating area with minimal copper heatsinking on the PCB.
