ONSEMI - Linear Voltage Regulator, Fixed, Positive Voltage, 10V to 35V, 5V Out, - 1A

The ONSEMI MC78M05BDTG is a 3-terminal positive voltage regulator designed for local and on-card voltage regulation. Specified for half the output current of standard 78 series regulators, it delivers a stable 5V output with a maximum output current of 500mA (with adequate heat sinking). This device is intended for industrial applications where reliable, regulated power is essential.

This regulator features internal current limiting, thermal overload protection, and output transistor safe-area compensation. These built-in protections ensure the device remains robust under most operating conditions, safeguarding both the regulator and the connected circuitry. The wide operating temperature range from -40°C to 125°C makes it suitable for demanding environments.

As a fixed-output, 3-terminal regulator, it requires no external components, simplifying circuit design and reducing board space. The surface-mount TO-252-3 package (DPAK) allows for efficient heat dissipation, especially when used with proper PCB copper area. Suitable for industrial power supplies, control systems, and other applications where a clean, stable 5V rail is required from a 10V to 35V input source.

Key Benefits:

• Stable 5V fixed output with up to 500mA output current
• Wide input voltage range (10V to 35V) for flexibility
• Internal current limiting and thermal overload protection for reliability
• No external components required, saving space and cost
• Surface mount package (TO-252-3 / DPAK) for compact designs
