LE45CD-TR is a medium power bi-directional resistor (as used mainly in linear voltage regulation) type voltage regulator. Its notable features are its compact size, low input voltage (to 6.5V), high efficiency, wide output voltage range (2.0V to 10V), and low power consumption. It is widely used in power amplifiers, audio amplifiers, home automation, tiny AC/DC converters, portable media players, small motor drives, storage applications, and numerous other applications.The LE45CD-TR is a low power device specifically designed for linear voltage regulation. It can be used to regulate the current, voltage, or power of a circuit. It has an adjustable output voltage, so it can be used to supply different voltages to the load. The input voltage can be limited by an input capacitor. Additionally, the LE45CD-TR has an adjustable current limit, which is useful to protect the circuits against current spikes or short circuits.The LE45CD-TR works by manipulating the voltage divider that is used to configure the output voltage. This is done by inserting a trimmer or a potentiometer into the voltage divider. The LE45CD-TR then alters the output voltage by measuring the voltage across the trimmer or potentiometer and accordingly adjusting its current output, ensuring a stable and reliable output voltage. By slightly modifying the voltage divider, the output voltage can be further adjusted.The LE45CD-TR has an adjustable current output and an adjustable maximum current output. The current output is adjusted by connecting a trimmer or potentiometer to the control input. The maximum current output is adjusted by connecting a resistor to the device’s current limit terminals. This makes it easy to control and monitor the current output of the device.The LE45CD-TR has a wide input voltage range of up to 10V and a wide output voltage range from 2.0V to 10V, making it suitable for a wide range of applications. Additionally, it draws only a minimal quiescent current of only 80uA and has an efficiency of up to 90%. This reduces the power consumption, prolongs the service life of the device, and also helps to save energy.In conclusion, the LE45CD-TR is a versatile and reliable medium power linear voltage regulator. Its wide input and output voltage ranges make it suitable for a wide range of applications. It has low input and output voltage capability, high efficiency and low quiescent current level, making it ideal for many types of automotive, industrial, and consumer electronics applications.
