LM2596T-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2596T-ADJ is a monolithic integrated circuit step-down switching regulator from the SIMPLE SWITCHER family, manufactured by TAEJIN. It operates with a fixed internal oscillator frequency of 150 kHz and supports an input voltage range of 4.5 V to 40 V. The device provides an adjustable output voltage ranging from 1.2 V to 37 V with a guaranteed tolerance of +/- 4% under maximum line and load conditions. It is capable of delivering a continuous output current of 3.0 A. The component utilizes a TO-220-5 through-hole package and includes thermal shutdown and current limit protection features.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific part number corresponds to the TAEJIN manufacturer rather than Texas Instruments or other legacy producers. Confirm the package type is TO-220-5 and check for moisture sensitivity level 3 compliance. Ensure the datasheet matches the 150 kHz switching frequency specification. Validate that the adjustable output version meets the required 1.2 V to 37 V range and 3.0 A current capacity for your application.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a robust, high-current buck converter is required with minimal external components. The adjustable output variant offers flexibility for custom voltage requirements compared to fixed versions. Consider the through-hole TO-220-5 package for applications requiring easy prototyping or higher thermal dissipation capabilities compared to surface-mount alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2596 series of SIMPLE SWITCHER power converters. It shares core architectural similarities with fixed-output variants such as the LM2596T-3.3, LM2596T-5.0, and LM2596T-12. All members of this series utilize the same 150 kHz switching frequency and 3.0 A current handling capabilities, differing primarily in their output voltage configuration and feedback network requirements.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2596T-ADJ/NOPB from Texas Instruments. Other compatible options within the same family are LM2596T-ADJ/LF02 and LM2596T-ADJ/LB05. Verify pinout compatibility and thermal performance characteristics before substituting.
