ONSEMI 78M05 SMD Voltage Regulator, +5.0V, DPAK-3 Package
ONSEMI 78M05 SMD linear voltage regulator. Fixed +5V output, 500mA, in TO-252 (DPAK-3) package. Ideal for PCB power regulation.
The ONSEMI 78M05CDTG is a fixed-output, three-terminal positive linear voltage regulator designed for reliable, on-card voltage regulation. Housed in a compact 3-pin TO-252 (DPAK-3) surface-mount package, this robust component is engineered to deliver a stable 5V output, making it an essential building block for a wide range of electronic circuits.
Engineered for durability, the regulator incorporates internal current limiting, thermal shutdown protection, and safe area compensation for the internal pass transistor. This combination of features ensures the device remains rugged and reliable under most operating conditions, protecting both the regulator and your circuitry from potential damage due to overloads or excessive heat.
A key advantage is its simplicity of use, requiring no external components for basic operation. It offers a peak output current of 700mA at 25°C, with a maximum continuous output current of 500mA. With a maximum input voltage of 35V and a typical dropout voltage of just 2V, it provides efficient regulation from a higher input supply. Its wide operating junction temperature range of 0°C to 125°C makes it suitable for industrial and commercial applications.
This component is ideal for providing local, regulated power to microcontrollers, sensors, logic circuits, and other 5V digital components, helping to eliminate noise and voltage fluctuations from the main supply rail. Its surface-mount design allows for efficient, high-density PCB assembly, saving valuable board space in modern electronic designs.
