The NJU7211U12 is a single-channel feature-packed low-dropout (LDO) linear voltage regulator from New Japan Radio. This voltage regulator is great for applications requiring a wide range of output currents, long-term stability, and excellent load and line regulation characteristics.

The NJU7211U12 is designed to deliver stable voltage with a wide input range of 2.5V to 25V. It allows stable output voltage of between 1.0V to 5.0V and adjustable current up to 10A. The dropout voltage of the NJU7211U12 is only 230mV at 10A, making it an ideal solution for low-voltage, low-power applications.

To ensure satisfactory performance, the NJU7211U12 utilises TO-220 full-mold package with a thermal resistance of 1.8°C/W. It also has on-chip high current ESD protection, over-temperature protection and short-circuit protection for high robustness in challenging environmental conditions. Additionally, the NJU7211U12 features low ground current, audible startup noise suppression and fast transient response.

The NJU7211U12 can be used in a variety of applications, such as communications systems and consumer electronics. It is an ideal voltage regulator for consumer electronics requiring tight regulation of output voltage and low quiescent current consumption. Furthermore, the excellent load and line regulation characteristics of the NJU7211U12 make it suitable for consumer audio and video products.

The NJU7211U12 operates on PWM (pulse width modulation) principle. It generates stable output voltage via closed-loop feedback that is modulated by the input voltage. In other words, the PWM modulation adjusts the duty cycle of the switching output in order to match the input voltage range. This precise regulation of the output voltage allows for stable system operation, even when faced with varying load and line conditions.

Overall, the NJU7211U12 is a robust, low-power and feature-packed single-channel linear voltage regulator with excellent load and line regulation characteristics. It is an ideal selection for consumer electronics, communications systems and any other application requiring precise output voltage regulation.
