Linear voltage regulators are necessary components of electronic systems. The LP38851S-ADJ is a high-efficiency 3A linear adjustable step-down DC-DC power regulator which can offer flexibility. It is ideal for applications requiring high performance and full system protection, such as powering memory, FPGAs, ASICs, and more.

The LP38851S-ADJ operates with an adjustable output, 2-25V range and a three-terminal fixed 2.5V reference. In addition, it incorporates under-voltage, over-voltage, current limit, and thermal shutdown protection circuits. It also provides gate drive for an external FET, to ensure fast and efficient output current usage.

The LP38851S-ADJ features a wide input voltage range and high efficiency, making it an ideal choice for applications with stringent power delivery requirements. With its adjustable output voltage, it is especially suitable for automotive, telecom, and industrial applications where precision current control and extreme power savings are needed.

The working principle of the LP38851S-ADJ is based on a three-terminal adjustable regulator integrated circuit, which consists of an error amplifier, an output power stage and an output voltage regulator. The error amplifier is used to monitor the output voltage and detect any changes between the reference voltage and the output voltage. When a discrepancy is detected, the error amplifier adjusts the output power stage in order to regulate the output voltage and maintain the correct voltage level.

The LP38851S-ADJ also provides an accurate current limit protection along with an over-voltage protection. It is also equipped with a high current gate drive to protect the output voltage from being overstressed. This makes the LP38851S-ADJ an ideal choice for applications requiring power savings, accuracy and high performance.

The LP38851S-ADJ is a high efficiency linear adjustable step-down DC-DC power regulator ideal for applications requiring high performance and full system protection. Its adjustable output voltage range, wide input voltage range, and high efficiency make it a perfect solution for applications where precision current control and extreme power savings are needed, such as in automotive, telecom, and industrial applications.
