LP3983ITL-1.6/NOPB is an advanced step-down, low dropout linear voltage regulator classified as a PMIC (power management integrated circuit). It is an integrated linear voltage regulator that efficiently regulates voltage levels ≤ΔV or as low as 0.5V to provide a low-noise output. The regime delivers low-noise, low-dropout voltage regulation, with excellent line and load transient performance, in a small surface mount package.

This voltage regulator features an integrated low-power start-up circuit, allowing the device to start-up with a low output voltage that gradually increases until it reaches the desired voltage. This eliminates the need for an external load switch, reducing design complexity and cost. In addition, it offers over-temperature protection (OTP) to protect the device from damaging high temperatures. The device can also enable a secondary power supply to be applied in parallel when the system does not require the full load current on the primary supply.

LP3983ITL-1.6/NOPB works on the principle of employing an internal resistor and a precise reference voltage to generate a precise output voltage. This reference voltage is supplied as an input to the device and is regulated by an internal control loop. The control loop compares the reference against the output voltage and adjusts the regulated circuit accordingly. As the job is to maintain a specified output voltage, the internal control loop of the regulator adjusts its duty cycle periodically so as to provide constant voltage at the output.

LP3983ITL-1.6/NOPB can be used in a variety of applications, such as consumer devices, computers, and portable electronics. It is ideally suited for applications requiring extremely low-noise operation, such as portable and audio/video systems, communications and consumer equipment. The device is also highly reliable and efficient, ensuring high performance in portable energy products and notebook power supplies.

LP3983ITL-1.6/NOPB offers an affordable, highly integrated, small package size choice for low noise, high accuracy, low power, low-dropout linear voltage regulation. This device is a reliable solution for microprocessor based systems, providing a low-dropout, low-noise voltage regulator for microcontroller and processor-based applications.

In summary, LP3983ITL-1.6/NOPB is a PMIC-Voltage Regulators-Linear device which works on the principle of employing an internal resistor and a precise reference voltage to generate a precise output voltage. The control loop compares the reference against the output voltage and adjusts the regulated circuit accordingly. The device is used in a variety of low-noise, high accuracy, low power, and low-dropout linear voltage regulation applications such as computers, consumer devices, portable electronics, audio devices and other microprocessor based systems.
