Key Features

  • Ultra-low quiescent current for extended battery life in portable applications
  • Fixed 3.3 V output with 0.5 V typical dropout voltage across 3.8 V to 6 V input range
  • Capless design eliminates output capacitor requirement, reducing BOM cost and board space
  • Compact SOT-23-5 package suits space-constrained wearable and IoT designs

Applications

The MCP1711T-33I/OT is well-suited for battery-powered IoT sensors, wearables, and wireless modules where minimizing quiescent current directly extends battery runtime. Its 3.3 V fixed output and capless architecture simplify power rail design in compact handheld instruments and portable medical devices. The wide input range of 3.8 V to 6 V also makes it compatible with single-cell Li-ion and 4-AA battery stacks.

Frequently Asked Questions

What is the dropout voltage of the MCP1711T-33I/OT under load?

The MCP1711T-33I/OT has a typical dropout voltage of 0.5 V and a maximum of 0.67 V, meaning the input supply must be at least 3.8 V to maintain the regulated 3.3 V output across the full operating temperature range.

Which battery chemistries are compatible with the MCP1711T-33I/OT input range?

With an input voltage range of 3.8 V to 6 V absolute maximum 6.5 V, the MCP1711T-33I/OT works with single-cell Li-ion (nominally 3.7 V to 4.2 V) as well as 3xAA alkaline packs, making it a versatile choice for portable battery-powered electronics.

How does the capless design of the MCP1711T-33I/OT benefit PCB layout?

Because the MCP1711T-33I/OT is designed to operate without an output capacitor, designers can eliminate at least one passive component, saving roughly 1 to 2 mm² of board area in the SOT-23-5 footprint and simplifying layout in space-constrained wearable or IoT modules.

In which thermal or environmental conditions does the MCP1711T-33I/OT qualify for industrial use?

The MCP1711T-33I/OT is rated for the industrial temperature grade, supporting operation across -40°C to +125°C, which meets requirements for outdoor sensor nodes, industrial monitoring equipment, and automotive-adjacent applications demanding wide temperature tolerance.
