What are the key features of MCP1726-1802E/MF?
- 1A output current with only 220mV typical dropout voltage at full load, enabling high-efficiency operation
- Integrated power-good (PG) output flag signals when output voltage is within regulation, simplifying system sequencing
- Ultra-compact 8-pin DFN package (3x2 mm) reduces PCB footprint in space-constrained portable and IoT designs
What is MCP1726-1802E/MF used for?
The MCP1726-1802E/MF is well suited for powering 1.8V logic rails in portable electronics, IoT sensor nodes, and microcontroller-based systems where board space is limited. Its low 220mV dropout makes it ideal for single-cell Li-ion or regulated 3.3V-to-1.8V conversion applications. The power-good output simplifies processor reset sequencing and supervisor circuit designs.

Frequently Asked Questions
What is the maximum continuous output current the MCP1726-1802E/MF can deliver, and what dropout voltage should I budget at full load?
The MCP1726-1802E/MF delivers up to 1A continuous output current. At full 1A load, the typical dropout voltage is 220mV and the maximum is 500mV, so you need at least 2.3V input to maintain a regulated 1.8V output across all process and temperature corners.
Can MCP1726-1802E/MF regulate from a 3.3V supply down to 1.8V in a battery-powered IoT device operating over a -40°C to +125°C temperature range?
Yes. With a 3.3V input the device has roughly 1.5V of headroom against the 500mV worst-case dropout, providing a comfortable margin at 1A across the full -40°C to +125°C industrial temperature range. The DFN-8 package also dissipates heat efficiently on compact PCBs.
How does the power-good (PG) pin work on the MCP1726, and what pull-up resistor value should I use?
The PG pin is an open-drain output that pulls low when the output voltage falls more than approximately 8% below the nominal 1.8V set point. Connect it through a 100kΩ pull-up resistor to any available rail up to 6V. The resulting logic signal can drive a microcontroller reset pin or a supervisor IC directly, with no additional comparator circuits required.
When is MCP1726-1802E/MF a better choice than a switching regulator for 1.8V generation from 3.3V?
For output currents up to 1A and input-to-output differentials of 1.5V, the LDO power dissipation is only 1.5W maximum, which is acceptable in many applications. The MCP1726 eliminates inductor, bootstrap capacitor, and EMI filtering costs, reducing BOM by 4–6 components while occupying under 20mm² of board area. It is the preferred choice when EMI sensitivity or design simplicity outweighs efficiency.
