The Texas Instruments LP38853SX-ADJ/NOPB is a low quiescent current, low dropout (LDO) linear voltage regulator. Its advanced design offers improved efficiencies over comparable linear voltage regulators for portable applications. It features an adjustable output voltage, over-voltage protection, and low standby power consumption, thus making it an ideal choice for powering high-end portable devices.

The LP38853SX-ADJ/NOPB is a true linear regulator, meaning that it provides very low output ripple, ensures tight regulation of the output voltage across the full operating temperature range, and provides a higher power efficiency rating than other types of voltage regulators. This linear regulator is designed to provide up to an adjustable and regulated output voltage of 2 V to 10 V with an input voltage of up to 24 V and a maximum output current of 2.5 A. An adjustable feedback voltage set point helps maximize the output voltage accuracy, while the adjustable output current limiting protects the LP38853SX-ADJ/NOPB from overheating and output current overloads.

The LP38853SX-ADJ/NOPB includes an adjustable current limit with a typical threshold of 0.95V and a precision enable/disable control pin with a typical turn-off threshold of 0.8 V. The device also includes adjustable soft-start, short circuit current limit, thermal shutdown protection, over-temperature protection and under-voltage lockout protection. Together with its low quiescent current, the LP38853SX-ADJ/NOPB is an ideal solution for powering high-end portable devices.

The LP38853SX-ADJ/NOPB can be used in a variety of applications such as power management of portable consumer electronics, including mobile phones, laptop computers, and tablets. It is also suitable for powering engine management systems in automotive applications, transceivers, industrial motors and LED lights.

The LP38853SX-ADJ/NOPB linear voltage regulator works on the principle of controlling the current to a load through a variable resistor. This variable resistor is connected to the output voltage that is to be regulated. Changes in the output are absorbed by the variable resistor, ensuring tight regulation of the output voltage. The variable resistor allows the output to be maintained in a steady state under varying conditions, providing the LP38853SX-ADJ/NOPB with excellent load and line regulation characteristics.

The LP38853SX-ADJ/NOPB linear voltage regulator offers high efficiency and low power consumption, along with excellent thermal and short-circuit protection. Its low quiescent current, high power efficiency rating, and adjustable output current limit make it well suited for powering high-end portable electronics. Its multiple protection features make it an ideal choice for automotive and industrial applications, where reliable operation is required.
