L78S09CV

Overview

The L78S09CV is a three-terminal positive linear voltage regulator from the STMicroelectronics L78Sxx series. It provides a fixed output voltage of 9V with a maximum output current capability of 2A. The device supports a maximum input voltage of 35V and operates within an ambient temperature range of 0°C to 150°C. Key electrical specifications include a typical static current of 8mA, line regulation of 130mV, and load regulation of 170mV. It utilizes a TO-220 package for through-hole mounting.

Feature Summary

Integrated thermal overload protection prevents damage during excessive heat conditions.
Internal short circuit protection safeguards the device against output faults.
Safe area protection ensures stability under varying load and voltage conditions.

Applications

General purpose power supply regulation
Local on-card voltage regulation
Battery chargers

Procurement Notes

Verify the specific revision status and RoHS compliance details directly with the manufacturer or authorized distributors before procurement. Confirm that the TO-220 package dimensions match the target PCB footprint requirements. Ensure adequate thermal management solutions are designed into the application to handle the power dissipation associated with the 2A output current capability.

Selection Notes

Select this component when a fixed 9V output at up to 2A is required in a robust through-hole package. Compare against the L78M09CV if lower current (500mA) is sufficient, as it may offer different thermal characteristics. Verify that the input voltage remains within the 35V maximum limit and consider the 150°C operating temperature range for high-temperature environments.

Part Context

The L78S09CV belongs to the L78Sxx series of three-terminal positive regulators, which bridges the performance gap between standard 1A regulators and higher-current industrial devices. This series is designed for local regulation applications, eliminating distribution problems associated with single-point regulation systems while providing essential internal protection features.
