What is MCP1790-5002E/DB used for?
The MCP1790-5002E/DB is suited for industrial 24 V bus systems requiring a stable 5 V rail for microcontrollers and sensors, given its 30 V maximum input. It is also used in automotive accessory boards where supply voltages fluctuate between 6 V and 16 V and a low-noise regulated 5 V output is needed. Its compact SOT-223 footprint fits space-constrained designs such as industrial I/O modules, fieldbus transceivers, and smart sensor nodes.

Frequently Asked Questions
What input voltage range does MCP1790-5002E/DB support for industrial 24 V bus designs?
The MCP1790-5002E/DB accepts input voltages from 6 V to 30 V, with an absolute maximum of 48 V. This wide range makes it compatible with standard 12 V and 24 V industrial bus rails, allowing a stable 5 V output without additional voltage conversion stages.
How much output current can MCP1790-5002E/DB supply and what is its dropout voltage?
The device delivers up to 70 mA of continuous output current. Its nominal dropout voltage is 0.7 V (maximum 1.3 V), so it maintains the 5 V regulated output as long as the input stays above approximately 6.3 V, which suits most 12 V and 24 V supply architectures.
How does the SOT-223 package of MCP1790-5002E/DB compare thermally to smaller LDO packages?
The SOT-223-3 package has a larger exposed pad compared to SOT-23 or SOT-89, reducing junction-to-board thermal resistance. At 70 mA load with a 25 V input-to-output differential, the package dissipates up to approximately 1.75 W, and the SOT-223 allows this without an external heatsink in most PCB configurations.
What output voltage accuracy does MCP1790-5002E/DB provide and why does that matter for sensor supply rails?
The MCP1790-5002E/DB guarantees ±2.5% output accuracy on its fixed 5 V rail, meaning the output stays between 4.875 V and 5.125 V across temperature and load. This level of precision is sufficient for powering 5 V ADC reference circuits, RS-485 transceivers, and microcontroller VDD pins in industrial sensor nodes.
