LM2878P – NATIONAL SEMICONDUCTOR

The National Semiconductor LM2878P is a monolithic integrated circuit specifically designed as a low-dropout (LDO) linear regulator optimized for battery-powered systems and portable applications. It delivers a stable output voltage with a very low quiescent current. Its primary function is to provide a regulated 5V output, making it suitable for powering microcontrollers and other digital logic. The LM2878P boasts a robust output current rating of 500mA, ensuring adequate power delivery for moderate loads. It is packaged in a through-hole TO-220 package, facilitating easy prototyping and heat dissipation. The device operates reliably across an operating temperature range of –40°C to 125°C. Its advantages include excellent transient response, short-circuit protection, and thermal shutdown, simplifying circuit design and enhancing system reliability. The output voltage is a steady 5V.
