Key Features
- Fixed 1.8 V output with up to 380 mA load current and only 380 mV maximum dropout voltage for efficient low-voltage rails
- Wide input range of 2.5 V to 5.5 V with absolute maximum rating of 6 V, compatible with single-cell Li-ion and USB power sources
- Ultra-compact VDFN-8 package minimizes PCB footprint for space-constrained portable and wearable designs
- Low quiescent current and stable operation with small ceramic output capacitors reduce BOM cost and board area
Applications
The MCP1810T-18I/J8A is ideal for supplying 1.8 V rails in portable devices such as wireless sensors, Bluetooth modules, and IoT nodes powered from Li-ion batteries or USB. Its low dropout voltage of 380 mV and 380 mA output capacity make it suitable for powering microcontrollers, FPGAs, and low-voltage logic in handheld instruments. The compact VDFN-8 form factor also fits point-of-load regulators on densely populated boards in industrial and consumer electronics.

Frequently Asked Questions
What is the output voltage and maximum load current of MCP1810T-18I/J8A?
The MCP1810T-18I/J8A provides a fixed 1.8 V output with a maximum continuous load current of 380 mA. Its maximum dropout voltage at full load is 380 mV, allowing it to regulate from input voltages as low as 2.5 V, which suits single-cell lithium-ion battery applications where headroom is limited.
Which input voltage range is supported by MCP1810T-18I/J8A and what is the absolute maximum?
The MCP1810T-18I/J8A operates with an input voltage between 2.5 V and 5.5 V, with an absolute maximum rating of 6 V. This wide range covers USB 5 V, 3.3 V rails, and single-cell Li-ion batteries from 3.0 V to 4.2 V, making the device versatile across many power-supply architectures in portable and industrial equipment.
How compact is the MCP1810T-18I/J8A package and what board space does it occupy?
The MCP1810T-18I/J8A uses a VDFN-8 (8-pin Very Thin Dual Flat No-Lead) package, which typically measures 2 mm × 3 mm with a height of 0.9 mm. This miniature footprint saves significant board space compared to SOT-223 or D2PAK regulators, making it a preferred choice for wearable devices, compact IoT modules, and densely populated multi-layer PCBs.
In which application scenarios does MCP1810T-18I/J8A outperform a switching regulator?
In low-noise analog and RF applications, the MCP1810T-18I/J8A excels because it introduces no switching noise that would degrade SNR in ADCs or RF front-ends operating at 1.8 V. For loads below 380 mA where the input-output differential is under 1 V, its linear dropout regulation is also more cost-effective and simpler to implement than a buck converter, requiring fewer external components and no inductor.
