NJM2845DL1-23-TE1 is a voltage regulator that is categorized under PMIC Voltage Regulators - Linear. It is a low-dropout (LDO) fixed voltage regulator, intended for use to generate output voltages that are lower than the input voltage. NJM2845DL1-23-TE1 has a wide array of features, including low quiescent current, shorter turn-on time, and minimal overshooting characteristics. These features make it an ideal choice for applications ranging from automotive and industrial to consumer electronics and IoT. The NJM2845DL1-23-TE1 is designed to provide a fixed output voltage over a wide input voltage range. It is available in several fixed output voltage options including 1.8V, 2.5V, 3.0V, 3.3V, 5.0V and adjustable voltage versions. The maximum supply voltage is typically 23V, while the quiescent current is 3mA or less. This LDO regulator has an output current capability up to 1A, and is suitable for a wide variety of applications. This regulator is equipped with a wide range of protection features, such as overcurrent protection, overvoltage protection, output voltage overshoot protection, reverse current protection, and thermal shutdown. Additionally, the NJM2845DL1-23-TE1 has an internal power transistor that provides high PSRR, low dropout voltage, and fast transient response. In terms of performance, the NJM2845DL1-23-TE1 excels due to its low output voltage ripple and excellent noise immunity. Its low output voltage ripple enables smoother operation and better response to high load current transients. In addition, the LDO regulator’s excellent noise immunity ensures that noise generated by other components in the system won’t adversely affect the output voltage. The working principle of NJM2845DL1-23-TE1 involves controlling the power transistor by comparing the voltage at the feedback pin with the internal reference voltage of 1.225V. When the reference voltage exceeds the feedback voltage, the power transistor is turned on, resulting in a voltage drop across the regulator. This voltage drop contributes to the output voltage, resulting in a constant voltage output. When it comes to application fields, the NJM2845DL1-23-TE1 is suitable for use in a wide range of applications. Its high power supply rejection ratio and fast transient response make it ideal for automotive and industrial applications which require high reliability, such as motor control, battery management and audio amplifiers. Its wide input voltage range and low quiescent current also make it suitable for consumer electronics, such as medical devices and portable electronics. Finally, since it allows for adjustable output voltages, the NJM2845DL1-23-TE1 can be used in IoT applications, such as home automation systems.Overall, the NJM2845DL1-23-TE1 is a versatile and robust low-dropout fixed voltage regulator. It offers excellent power supply rejection, fast transient response and low quiescent current, making it suitable for a wide range of applications, from automotive and industrial, to consumer electronics and IoT. With features such as overcurrent, overvoltage, output voltage overshoot protection, and thermal shutdown, the NJM2845DL1-23-TE1 ensures reliable operation in all of its applications.
