STMICROELECTRONICS L78S15CV Voltage Regulator

The L78S15CV is a three-terminal positive voltage regulator designed to provide local on-card regulation, eliminating distribution losses. It features internal current limiting, thermal shutdown, and safe area protection, ensuring high reliability and resistance to damage. Capable of delivering over 2A with proper heat sinking, it is primarily a fixed voltage regulator but can be used externally for adjustable outputs. Suitable for power management and regulatory applications, it offers robust protection features and consistent performance under varied conditions. Extended lead times are common due to high demand, and discounts are not applicable.
