STMicroelectronics L78M24CV, 1-Channel Low Dropout Voltage, Voltage Regulator, 500 mA, 5/24 V, TO-220 3-Pin

The STMicroelectronics regulator, This regulator can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type employs internal current limiting, thermal shutdown and safe area protection, resulting it essentially indestructible. If adequate heat sinking is provided, they can deliver over 0.5 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents.
