Key Features
- 1A output current with only 220mV typical dropout voltage enables high-efficiency regulation close to the input rail
- Adjustable output voltage configuration provides flexibility for diverse supply rail requirements in a single BOM entry
- 0.3%/V line regulation and CMOS architecture minimize output variation across input voltage changes
- SOIC-8 package with RoHS-compliant e3 JEDEC moisture sensitivity rating simplifies industrial and consumer assembly
Applications
The MCP1726T-ADJE/SN is used in portable consumer electronics, battery-powered instruments, and IoT edge nodes where minimizing dropout voltage to 220mV directly extends battery run time. Industrial sensor modules and embedded systems benefit from its 1A current capability and stable line regulation of 0.3%/V, supporting mixed-voltage boards that need adjustable LDO rails from a common 5V or 3.3V bus. Its adjustable configuration also makes it a practical choice for prototyping boards and evaluation kits requiring flexible output voltage settings.

Frequently Asked Questions
How low a dropout voltage does the MCP1726T-ADJE/SN maintain at full 1A load, and why does that matter for Li-ion battery designs?
The MCP1726T-ADJE/SN maintains a typical dropout voltage of only 220mV at 1A output, which is critical for single-cell Li-ion designs because it allows regulation to continue until the battery discharges to approximately 3.5V, extending useful runtime compared to regulators with 500mV or higher dropout.
Which adjustable output voltage range can be set with the MCP1726T-ADJE/SN, and what external components are required?
The MCP1726T-ADJE/SN supports an adjustable output voltage set by two external resistors, covering supply rails commonly between 1.2V and the input voltage minus the 220mV typical dropout, requiring only a bypass capacitor of a few µF on the output to ensure stability at 1A load.
For an industrial sensor node drawing up to 800mA from a 5V rail, how does the MCP1726T-ADJE/SN compare to a fixed-output LDO?
The MCP1726T-ADJE/SN delivers up to 1A from a 5V rail with 0.3%/V line regulation, outperforming many fixed-output LDOs in flexibility because one adjustable part covers multiple output voltages, reducing inventory SKUs while meeting the 800mA load requirement with a 220mV typical dropout versus a 500mV dropout in fixed alternatives.
What is the JEDEC moisture sensitivity rating of the MCP1726T-ADJE/SN, and what does it mean for production handling?
The MCP1726T-ADJE/SN carries a JEDEC e3 (MSL 3) moisture sensitivity classification, meaning components must be soldered within 168 hours of removing them from sealed dry-pack at 30°C and 60% relative humidity, which is a standard production floor life manageable in most contract manufacturing environments.
