series introduction
The KA78M05 Series is a family of fixed-output voltage regulators designed to deliver reliable and stable power supply solutions in a wide range of electronic applications. These linear voltage regulators are engineered to provide a constant 5V output voltage, making them ideal for powering low-voltage circuits and components. With a maximum output current of 500mA, the KA78M05 Series is well-suited for applications requiring moderate power delivery while maintaining high efficiency and thermal performance.
One of the standout features of the KA78M05 Series is its robust design, which incorporates built-in thermal overload protection and short-circuit protection. These safety mechanisms ensure the regulators can operate reliably even under challenging conditions, such as high ambient temperatures or sudden load changes. Additionally, the series features low dropout voltage, enabling it to maintain stable output even when the input voltage is close to the output level. This makes the KA78M05 Series particularly useful in battery-powered devices or systems with fluctuating input voltages.
The compact TO-252 (DPAK) package of the KA78M05 Series is designed for easy integration into space-constrained applications, while its surface-mount design simplifies assembly processes in modern manufacturing environments. The series is also characterized by its low quiescent current, which minimizes power consumption during standby or light-load conditions, further enhancing its suitability for energy-efficient designs.
Typical applications for the KA78M05 Series include powering microcontrollers, sensors, and other low-power components in consumer electronics, automotive systems, and industrial equipment. Its ability to deliver consistent performance across a wide temperature range (-40°C to +125°C) makes it a reliable choice for environments with varying thermal conditions. Whether used in portable devices, embedded systems, or power management modules, the KA78M05 Series offers a dependable and cost-effective solution for maintaining stable voltage levels in electronic circuits.
