MSC750SMA120S

The MSC750SMA120S is a special type of power supply specially developed for use in the industrial, automotive and aerospace field. It is designed to operate in an extremely wide range of temperatures, from -55°C to +125°C, and also features a long life and predictable power efficiency. For these reasons, the MSC750SMA120S finds application in a variety of extreme environment settings.

The core of the MSC750SMA120S is what is known as an ultra-low dropout voltage regulator (LDO). This is a form of voltage regulator which provides a very precise output voltage, independent of varying load and input voltage. This makes it ideal for applications where consistent and precise output voltages are needed, regardless of changing conditions.

This LDO voltage regulator works through use of two transistors and an external sense resistor. This is a method known as transconductance regulation, and can be used in additional power supply designs. This component is the key piece in the MSC750SMA120’s design, as it allows for the extremely wide range of temperatures and life expectancy stated above.

The transistors at the heart of the regulator work together to keep a level input voltage at an input side. When the load calls for more current than the output voltage can supply, the sense resistor signals the transistors to switch on, causing current to be directed to the output side accordingly. This switch on action increases both the input voltage and the output voltage, allowing the output voltage to stay consistent and precise.

This regulation system ensures that the output voltage stays the same throughout a wide range of varying loads, temperatures, and inputs. With its low drift and output voltage accuracy of 0.5%, the MSC750SMA120S has become a top choice for many industries.

These are just some of the reasons why the MSC750SMA120S has effectively found its way into a variety of different applications. Its low dropout voltage allows it to use in a range of systems with tough environmental conditions, while its sense resistors give it the precision voltage accuracy necessary for use in many different industries.

From radio communication systems to aerospace, the MSC750SMA120S is the ideal choice for many applications in these fields. Furthermore, its long life and reliable performance ensure a longer usage cycle and fewer maintenance costs, making it a great choice for any system.
