LM2575D2T-ADJR4G is listed in the Voltage Regulators - DC DC Switching Regulators range at ChipApex. The manufacturer field lists onsemi. Its product description is IC REG BUCK ADJ 1A D2PAK-5. Review the specifications below when checking this part for your BOM.
The LM2575D2T-ADJR4G is a step-down switching regulator IC from onsemi, part of the LM2575 series. It operates with an input voltage range of 4.75 V to 40 V and provides a fixed output current capability of 1 A. The device utilizes a buck topology with a standard switching frequency of 52 kHz. It features an adjustable output voltage configuration housed in a TO-263-5 (D2PAK-5) surface-mount package. The component supports a junction temperature operating range from -40 °C to +125 °C.
Verify the specific suffix ADJR4G against the manufacturer datasheet to confirm the adjustable output variant and reel packaging format. Ensure compatibility with RoHS and REACH requirements for the target region. Cross-reference the D2PAK-5 pinout with the design schematic to prevent installation errors during assembly.
Select this component when an adjustable output voltage is required within the 1 A load range. The wide input voltage range suits applications with varying supply rails. Consider the thermal performance of the D2PAK-5 package for heat dissipation needs in enclosed environments compared to smaller packages.
This part belongs to the LM2575 family of simple-switcher regulators. It shares core architecture with fixed-voltage variants like the LM2575D2T-5G but differs in output configuration. The D2T suffix indicates the surface-mount D2PAK-5 package type, distinguishing it from through-hole or other package options within the same product line.
