78M05 SMD Fixed Dropout Regulators 5V 6mA TO-252
The 78M05 SMD Fixed Voltage Regulator is a reliable linear regulator designed to deliver a constant 5V output from a higher input voltage. Built in a TO-252 (DPAK) surface-mount package, it is ideal for compact PCB designs where space efficiency and thermal performance are important. This regulator is commonly used in power supply sections of electronic circuits to ensure stable voltage for sensitive components.
With built-in protection features and simple implementation, the 78M05 is widely adopted in consumer electronics, industrial control systems, and embedded designs. It requires minimal external components, making it easy to integrate into both professional and DIY projects. Its robust construction and stable output make it suitable for powering microcontrollers, sensors, and logic circuits.
