Introduction

The LP2967IBPX-1833 is a linear voltage regulator from Texas Instruments. This regulator is used to regulate the output voltage of low-cost supplies and provide a low voltage dropout voltage. The device can be configured to provide a complete power solution.

Application Field

The LP2967IBPX-1833 is widely used in general-purpose applications to provide a reliable and low-cost solution. It is ideal for applications such as handheld electronics, wireless communications, and laptop computers. The device features a high efficiency and low output noise, which is suitable for any low voltage requirement. Additionally, the device can also be used for high-capacity DC power supplies where a low dropout voltage is required.

Features

The LP2967IBPX-1833 includes several features to improve its performance and make it suitable for different applications. It is a low dropout voltage regulator with a dropout voltage of up to 1V. It provides a high current output of up to 2A, allowing it to be used in applications that require high current output. The device also includes a wide input voltage range, from 1V to 18V. This makes the device suitable for applications that require input voltages from a wide range of sources. Additionally, the device has a low quiescent current of only 5mA, ensuring minimal power consumption at the same time.

Working Principle

The LP2967IBPX-1833 works as a linear voltage regulator, where the principle of operation is based on controlling the current of the output device. When the output voltage is greater than the set voltage, the device will reduce its current output, thus regulating the output voltage.The device features an error amplifier that compares the output voltage to a reference voltage. The output of the error amplifier will control the base voltage of the PNP transistor, which then controls the current output of the device. The device also includes an input voltage protection circuit that prevents the voltage from overflowing. This protection is also effective for input transients or drops below the set voltage.
