Key Features
- 500 mA output current with only 0.1 V typical dropout voltage enables efficient regulation from near-unity input-output ratios in single-cell Li-Ion applications
- Fixed and adjustable output configuration options allow one part to cover multiple rails in a design, reducing SKU count and simplifying BOM management
- 8-pin uMAX ultra-small package with 0.0113% maximum line regulation provides precise, compact voltage regulation for space-constrained portable and wearable designs
Applications
The MAX1806EUA18+T is suited for portable consumer electronics, wearables, and handheld medical devices where a compact 500 mA LDO with very low 0.1 V dropout helps extend battery run time near end-of-discharge. Its adjustable output option allows a single regulator to supply multiple voltage levels such as 1.8 V and 2.5 V in multi-rail IoT devices. The uMAX package footprint occupies under 9 mm² of PCB area, fitting into densely populated smartwatch and sensor node boards.

Frequently Asked Questions
How low is the dropout voltage of the MAX1806EUA18+T, and how does it affect Li-Ion battery life?
The MAX1806EUA18+T has a typical dropout voltage of only 0.1 V, allowing it to regulate a 1.8 V output from a Li-Ion cell down to approximately 1.9 V input; this extends usable battery capacity compared to LDOs with 0.3 V or higher dropout that cut out earlier in the discharge curve.
What output current does the MAX1806EUA18+T support, and what loads can it power?
The MAX1806EUA18+T delivers up to 500 mA continuous output current, sufficient to power microcontrollers drawing 100 mA to 200 mA, wireless radio modules at 300 mA peak, and small LCD panels, making it a versatile single-chip regulator for portable multi-peripheral systems.
When is the adjustable output mode of the MAX1806EUA18+T more useful than a fixed 1.8 V version?
The adjustable mode is more useful when a design requires a non-standard rail such as 1.5 V, 2.0 V, or 2.85 V that is not covered by fixed-output variants; two external resistors set the output, allowing engineers to prototype multiple voltage options from a single part number and reduce safety stock across board revisions.
How does the uMAX package size of the MAX1806EUA18+T compare to standard SOT-223 regulators in space-constrained designs?
The 8-pin uMAX package occupies under 9 mm² of PCB area compared to the SOT-223's approximately 20 mm², reducing regulator footprint by more than 50%; this directly benefits smartwatches, hearing aids, and miniature IoT nodes where every square millimeter of board space is allocated to batteries or sensors.
