NJM78L20UA-TE1 is a kind of positive and negative voltage regulator integrated circuit manufactured by Japan New Japan Radio Company (NJR). It is used for stabilizing the output voltage and current of a circuit and is generally used in audio and power supplies. This NJM78L20UA-TE1 is a three-terminal voltage regulator with a single output voltage of ±20V, and a maximum current output of 500mA. This IC offers a very low noise and low input offset voltage, which makes it ideal for use in audio applications.The NJM78L20UA-TE1 operates in open-loop and closed-loop modes to provide stable output voltage and current. In the open-loop mode, it acts as a simple voltage regulator, where the input and output voltages are equal. The output can be adjusted by controlling the voltage difference between the input and output. When the input voltage is lower than the output voltage, the output voltage will increase, and when the input voltage is higher than the output voltage, the output voltage will decrease.In the closed-loop mode, the NJM78L20UA-TE1 operates as an amplification device. An external feedback resistor controls the gain of the device. The gain of the device is determined by the feedback resistor, and it can be adjusted accordingly. The voltage output is compared to a reference voltage, then regulated to maintain a constant voltage.The features of the NJM78L20UA-TE1 include low temperature drift, low power consumption, improved linearity and accuracy, and fast transient response. The device operates over a wide range of temperatures, allowing it to be used in applications where temperature variations occur. This IC also has very good ripple rejection, making it ideal for use in applications where a constant voltage is required.The primary application field of the NJM78L20UA-TE1 is audio applications, including power amplifiers, audio mixers and sound processing circuits. It is also used in precision control circuits and power supplies, as well as in automation systems. The device\'s improved linearity and accuracy make it ideal for use in applications where a high level of accuracy is needed.In conclusion, the NJM78L20UA-TE1 is a three-terminal linear voltage regulator manufactured by Japan New Japan Radio Company (NJR). It features a single output voltage of ±20V and a maximum current output of 500mA. The device operates in open-loop and closed-loop modes providing a stable output voltage and current.
