Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates the through-hole TO-220 packaging variant distinct from surface-mount versions. Confirm RoHS compliance status as documentation may indicate non-compliance depending on manufacturing origin. Ensure the supplier provides official datasheets matching the Texas Instruments part number to validate electrical parameters and pinout configuration before integration into designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 3.3 V output is required without external feedback resistors. Choose the through-hole TO-220 package for applications prioritizing thermal dissipation capabilities over board space constraints. Consider the 2.6 A output capability against load requirements, noting that peak currents may exceed nominal ratings under specific transient conditions defined in the technical specifications.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2595 series of SIMPLE SWITCHER power converters. It shares architectural similarities with other variants in the family but differs in output voltage configuration and package type. The series is designed for straightforward implementation of buck converters, offering a balance between performance and simplicity compared to more complex programmable regulator solutions available from the manufacturer.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LM2595 variants with identical pinouts and functionality but different output voltages or packages, such as LM2595T-ADJ for adjustable outputs. Cross-family replacements like the LM2596 series offer similar topology but higher current ratings. Verify thermal management requirements and input voltage compatibility when substituting with related components.
