( Brand: Fairchild Semiconductor ), ( Manufacturer Part Number: UA78M15HC ), ( Part Type: Regulator )
The UA78M15HC semiconductor bench IC, manufactured by Fairchild in 1978, is a 5A, 15V voltage regulator. This device is designed to provide a stable and regulated output voltage, even under varying input voltage conditions.
The UA78M15HC is a three-terminal regulator, with the input terminal (IN), the output terminal (OUT), and the ground terminal (GND). The device is capable of delivering a maximum current of 5 amperes, making it suitable for powering a wide range of electronic components and circuits. The output voltage is continuously regulated to 15 volts, providing a stable power source for devices that require a constant voltage supply.
The UA78M15HC is a linear regulator, which means it regulates the output voltage by dissipating excess power as heat. This can lead to a higher power consumption compared to switch-mode regulators, but it also offers a number of advantages, such as a lower noise level and a simpler design.
The UA78M15HC is housed in a TO-220 package, which is a common package for linear regulators. The package size is 22mm x 10mm, making it a compact and easy-to-use solution for power supply applications.
Overall, the UA78M15HC semiconductor bench IC is a reliable and versatile voltage regulator, suitable for use in a wide range of electronic applications. Its high current capacity and stable output voltage make it a popular choice for powering a variety of electronic devices.
