Applications
The MCP1826-ADJE/AT is well-suited for portable consumer electronics, battery management systems, and embedded computing boards where a low-dropout adjustable regulator is needed with minimal input-to-output voltage difference. Its 1 A current capability and low 0.25 V dropout make it ideal for powering microcontrollers, FPGAs, and communication modules from Li-ion or single-cell battery sources. Industrial equipment and automotive accessory designs also benefit from its adjustable output and robust TO-220-5 thermal dissipation.

Frequently Asked Questions
What is the minimum dropout voltage of the MCP1826-ADJE/AT and why does it matter for battery-powered designs?
The MCP1826-ADJE/AT has a typical dropout voltage of 0.25 V and a maximum of 0.4 V at full load, which means the input supply only needs to exceed the output by 0.4 V to maintain regulation. This low dropout is critical for Li-ion battery applications where the cell voltage can drop to 3.0 V near end-of-discharge, allowing a 2.6 V regulated output to remain stable across a wider portion of the battery's discharge curve compared to standard LDOs.
How is the output voltage set on the MCP1826-ADJE/AT adjustable LDO regulator?
Because the MCP1826-ADJE/AT is an adjustable variant, output voltage is set using an external resistor divider connected between the output, the ADJ pin, and ground. The internal reference voltage and resistor ratio determine the regulated output level, providing design flexibility to target any voltage within the device's supported range. The 5-pin TO-220-5 package includes dedicated pins for this adjustment network alongside input, output, and ground connections.
Which industrial or embedded applications benefit most from the MCP1826-ADJE/AT in a TO-220-5 package?
Industrial sensor nodes, motor driver bias rails, and embedded computing boards powering 1 A loads all benefit from the MCP1826-ADJE/AT. The TO-220-5 package's exposed tab allows heatsinking to dissipate power at full load, making it practical for continuous 1 A operation across a -40°C to +125°C temperature range. Its line regulation of 0.2 %/V ensures the output stays stable even when the upstream supply fluctuates.
Is the MCP1826-ADJE/AT RoHS compliant, and what does its factory lead time look like?
Yes, the MCP1826-ADJE/AT carries Pb-free (RoHS) status with JESD-609 e3 classification, confirming it meets current environmental standards for halogen-aware and lead-free manufacturing. The typical factory lead time is approximately 7 weeks, so procurement planning should account for this when designing production schedules, and buffer stock of at least a few hundred units is advisable for volume builds using this 1 A adjustable LDO.
