Working Principle

The main purpose of the NJM2846DL3-23-TE1 voltage regulator is to maintain a stable and constant output voltage, even in a varying input voltage. This is achieved using linear voltage regulators, which employ the use of a feedback circuit that senses the output voltage and adjusts the feedback control to ensure a stable voltage.In the NJM2846DL3-23-TE1, the voltage regulation is done using a pass transistor, which is controlled by the feedback signal. This signal is fed back to the regulator, which then adjusts the pass transistor\'s gate voltage to maintain the output voltage.When the voltage is too low, the feedback signal instructs the gate voltage to be raised, and hence the output voltage is raised too. Similarly, when the voltage is too high, the feedback signal instructs the gate voltage to be lowered, thus lowering the output voltage.Therefore, the NJM2846DL3-23-TE1 can regulate the output voltage over a wide range of input voltages, ensuring a constant output voltage is maintained.

Conclusion

NJM2846DL3-23-TE1 is a linear voltage regulator manufactured by Japanese company NJRC. It has a wide adjustable output voltage range of between 2.2V to 6.2V and a wide operating temperature range of between -20°C and 70°C, making it suitable for a variety of applications, such as in mobile phones and automotive applications. The voltage regulation is done using a pass transistor, which is controlled by the feedback signal. This ensures the output voltage is regulated over a wide range of input voltages.
