COM-12766

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The SparkFun COM-12766 is a linear voltage regulator breakout board featuring the L7812 integrated circuit. It provides a fixed +12V DC output from an input voltage range typically exceeding 14V. The module utilizes a three-terminal TO-220 style package for robust heat dissipation. Designed for prototyping, it includes standard mounting holes and pin headers for easy integration into breadboards or custom PCBs. This component serves as a reliable power source for digital logic circuits requiring a stable 12V rail.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify that the specific revision of the COM-12766 matches your schematic requirements regarding pinout orientation and thermal pad configuration. Confirm input voltage limits do not exceed the maximum rating for the L7812 to prevent thermal shutdown. Ensure adequate heatsinking is applied if the current load approaches the regulator's continuous limit. Check for any updated documentation from SparkFun regarding component substitutions or pin definition changes.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this module when a simple, low-noise 12V supply is needed for low-to-moderate current applications. It is suitable for designs where efficiency is less critical than simplicity and cost. Consider alternative switching regulators if high current draw or significant input-output voltage differentials cause excessive heat generation. Ideal for hobbyist projects and initial proof-of-concept stages.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

SparkFun Electronics specializes in creating accessible development tools and breakout boards for engineers and educators. The COM-12766 is part of their broader catalog of power management accessories, designed to simplify the integration of common discrete components into larger embedded systems.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct functional equivalents include other L7812-based breakout boards from manufacturers like Adafruit or generic suppliers. For non-breakout implementations, the standalone STMicroelectronics L7812CV or Texas Instruments LM7812 can be used with appropriate external capacitors. Ensure any substitute maintains the same three-terminal TO-220 package for compatible mounting.
