LD2980CM50TR are linear voltage regulators which are mainly used in power electronic designs. Their application field covers military and aerospace, automotive, telecommunications, industrial, and consumer applications.

In applications where small amounts of input-output voltage differentials are accepted, such as in notebook computers, a LD2980CM50TR could potentially replace larger linear voltage regulators which is more commonly used.

LD2980CM50TR works by comparing the magnitude of ‘reference’ voltage,usually provided by an internal band gap reference generator, to the voltage at its input pins. As output voltage increases, the ‘error’ voltage, determined as the difference between the reference voltage and the input voltage, decreases. This decrease in the error voltage is sensed by the internal comparator inside the device which, in turn, reduces the output current inform of a feedback loop. When the output voltage reaches its steady state, the error Voltage is zero and if this condition is changed, the comparator will decrease or increase the output voltage until equilibrium is reached.

LD2980CM50TR comes in a low-profile 9-lead SOT-223 package and the operating ambient temperature range specified is from -55°C to 125°C. It is designed with a wide input voltage range making it possible to use it in air vehicles and AC/DC power systems. In addition, the LD2980CM50TR is RoHs compliant and Pb-free and is characterized for both commercial and industrial temperature ranges.

The LD2980CM50TR offers a wide range of features that makes it well-suited for use in many applications, some of which include power management, computing, automotive and industrial electronic applications. It offer adjustable output voltages and high input voltage of up to 50V. LD2980CM50TR also offers Protection Capabilities with the usual Over-Current protection, Over-Temperature protection and Reverse-Current protection. It also has fast transient response, current limiter, and thermal shutdown.

In summary, LD2980CM50TR is a linear voltage regulator that can replace larger linear voltage regulators when used in applications where small differentials between input and output voltage are accepted. It has a low-profile package of 9-lead SOT-223, wide operating temperature range from -55°C to 125°C and input voltage range of up to 50V. It offers a wide range of features, making it suitable for use in power management, computing, automotive and industrial electronic applications. As it is RoHs compliant and Pb-free, the LD2980CM50TR is suitable for use in a variety of applications.
