NJU7231U12-TE1 is a linear regulator that belongs to the PMIC (Power Management Integrated Circuit) family. It is a low dropout, low current regulator with a low output voltage range from 1.2 V to 6 V with a maximum output current of 500 mA. In addition, the device features thermal shutdown protection, an over-temperature protection circuit, and under-voltage lockout.

As one of the most common voltage regulators, NJU7231U12-TE1 boasts a wide range of applications. It can be used in digital audio and video equipment, appliances, small electronic devices, automotive electronics, and more. In automotive applications it is used to regulate voltages for headlights, taillights, fans and other components. Additionally, it can be used in microcontrollers to ensure stable power supply and accurate voltage.

The working principle of the NJU7231U12-TE1 linear regulator is relatively simple. It consists of an input terminal, output terminal and an error amplifier. When an input voltage is applied, the output voltage is determined by a reference voltage and the error amplifier, and the voltage is regulated by the pass element in order to keep the output voltage in the correct voltage range. The pass element, either a PMOS or NMOS transistor, is used to control the current passing through the load, and the control voltage applied to the pass element controls the speed of the current passing through the load.

The NJU7231U12-TE1 linear regulator has a high efficiency and is suitable for low current applications. In addition, the device features a low dropout voltage, allowing it to supply an output voltage very close to the input voltage. The over-temperature protection circuit, together with the thermal shutdown protection, provides additional protection for the device, making it an ideal choice for many applications.
