STMicroelectronics L78M Series — 0.5 A Positive Voltage Regulators

Description

The STMicroelectronics L78M series is a reliable three-terminal positive voltage regulator available in various fixed output voltages. Designed for local on-card voltage regulation, it helps eliminate distribution issues. With built-in thermal and short-circuit protection, it ensures robust operation in harsh conditions, providing output currents up to 0.5 A when adequately heat-sinked. These regulators can also be used with external components for adjustable voltage applications.
