COM-00107

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

The SparkFun COM-00107 is a linear voltage regulator IC based on the L7805 component. It provides a fixed positive output voltage of 5V with a maximum output current capability of 1.5A. The device utilizes a TO-220 package, which facilitates heat dissipation for stable operation under load. This three-terminal regulator is designed to maintain a constant output voltage despite variations in input voltage or load conditions, serving as a fundamental power management solution for electronic circuits requiring a reliable 5V supply rail.

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

Verify the specific manufacturer of the L7805 die used in the SparkFun assembly, as original equipment manufacturers may vary while maintaining the same pinout and electrical specifications. Confirm that the TO-220 package variant matches your thermal requirements and mounting constraints. Ensure input voltage remains within safe operating limits to prevent excessive power dissipation without adequate heatsinking.

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

Select this component when a simple, low-cost solution for generating a stable 5V rail is required from a higher input voltage source. Consider the thermal performance of the TO-220 package relative to the expected current draw and ambient temperature. Evaluate if linear regulation efficiency meets your system's power budget compared to switching alternatives for high-current applications.
