L7815CV

Overview

The UMW L7815CV is a positive fixed linear voltage regulator belonging to the L78xx series. It provides a nominal output voltage of 15V with a maximum output current capability of 1.5A. The device utilizes a TO-220-3 through-hole package and operates within an ambient temperature range of -40°C to +125°C. Internal circuitry includes overcurrent protection, thermal shutdown, and safe area protection to ensure reliability under fault conditions.

Feature Summary

• Fixed 15V output regulation for stable power supply applications
• Integrated thermal overload and short-circuit current limiting protection
• Designed for direct replacement in legacy three-terminal regulator circuits

Applications

• General-purpose positive DC power supplies
• Local on-card regulation for distributed power systems
• Embedded equipment requiring stable 15V bias voltages

Procurement Notes

Verify the manufacturer marking matches UMW specifications upon receipt. Confirm the package type is TO-220-3 and the suffix indicates standard commercial/industrial grade. Ensure the component meets RoHS requirements if mandated by the design specification. Cross-reference datasheets from authorized distributors to confirm pinout compatibility.

Selection Notes

Select this component when a fixed 15V output at up to 1.5A is required. Ensure the input voltage remains sufficiently higher than the output to maintain dropout voltage margins. Verify that the thermal management solution supports the expected power dissipation at the target load current and ambient temperature.

Part Context

This part belongs to the widely adopted L78xx family of three-terminal positive linear regulators. These devices are industry-standard replacements for older LM78xx designs. The L7815CV specifically targets applications needing a regulated 15V rail, offering robust performance in consumer and industrial electronics.
