L7810CV

Overview

The L7810CV is a fixed positive linear voltage regulator manufactured by STMicroelectronics, delivering a nominal output of 10 V with a maximum continuous load current of 1.5 A. It operates within an input voltage range of 12 V to 35 V and features internal thermal overload and short-circuit protection. The device utilizes a TO-220-3 through-hole package, ensuring robust mechanical stability for industrial applications. It maintains operation across a temperature range from 0 °C to +125 °C, providing reliable power management in environments requiring stable DC voltage conversion.

Feature Summary

• Fixed 10 V output regulation with integrated thermal and short-circuit protection
• High current capability up to 1.5 A without external heat sinks under moderate conditions
• Internal overcurrent limiting and thermal shutdown mechanisms ensure operational safety

Applications

• General-purpose power supply circuits requiring stable 10 V rails
• Battery-powered systems needing regulated voltage conversion
• Industrial equipment control logic power distribution

Procurement Notes

Verify the specific suffix designation against official STMicroelectronics documentation to confirm exact electrical tolerances and packaging variations. Ensure the procurement channel provides genuine components with traceable manufacturing dates. Cross-reference the part number with the latest datasheet revision to confirm compliance with current environmental standards such as RoHS. Confirm that the supplier offers valid warranty terms for electronic components.

Selection Notes

Select this component when a fixed 10 V output is required with high current capacity. Consider the thermal dissipation requirements based on the input-output voltage differential and load current. Evaluate the need for external capacitors at the input and output terminals to prevent oscillation. Compare performance metrics against alternative regulators if lower dropout voltage or adjustable output is necessary for the specific design constraints.

Part Context

This component belongs to the L78xx series of three-terminal positive linear regulators produced by STMicroelectronics. The series is widely recognized for its simplicity and reliability in basic voltage regulation tasks. The L7810CV specifically denotes the 10 V variant within this family, sharing common pinouts and protective features with other members like the L7805CV or L7812CV.

Replacement Considerations

Compatible substitutes include the LM7810CT from ON Semiconductor and the MC78M10CDT from onsemi. Verify pin compatibility and thermal characteristics before substitution. Ensure the replacement part meets the same 1.5 A current rating and 35 V maximum input voltage specifications.
