The LP2967ITPX-2833/NOPB is a Linear Voltage regulator that belongs to the PMIC (Power Management IC) family. It is a low drop-out voltage regulator which is designed to provide a very low output voltage of 4 percent. It is a high performance voltage regulator capable of operating from an input voltage range from 4.5V to 17V and delivering up to 1A of output current.

The LP2967ITPX-2833/NOPB can be used in a wide range of applications including consumer electronics, industrial controls, automotive, and medical products. The device offers excellent load and line regulation and good ripple rejection, making it ideal for many applications. It also provides over-voltage protection, current limiting, and thermal shutdown functions.

The working principle of the LP2967ITPX-2833/NOPB is based on a linear regulator with a fixed output voltage. This voltage is set by two resistors connected to an adjustable reference voltage. The output voltage remains constant regardless of the input voltage or the changes in the load current.

The variable output voltage is generated using a variable reference voltage and an internal error amplifier. The variable reference voltage is generated using an adjustable resistor divider. The error amplifier senses the output voltage and the reference voltage and compares the two. If the output voltage is lower than the reference voltage, the error amplifier increases the reference voltage and thus the output voltage. The opposite happens if the output voltage is higher than the reference voltage.

The LP2967ITPX-2833/NOPB also features over-voltage protection, current-limiting and thermal shutdown functions. The over-voltage protection limits the output voltage to a predefined level and the current limitation is activated when the load current exceeds the specified limit. The thermal shutdown feature protects the device from overheating by disabling the drive to the pass transistor and shutting the device down.

The LP2967ITPX-2833/NOPB is a versatile Linear Voltage Regulator and is suitable for many applications requiring a stable output voltage with minimal output voltage deviation. It offers excellent load and line regulation and good ripple rejection. Moreover, it also provides over-voltage protection, current limiting and thermal shutdown for protection in case of overload conditions.
