Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as Texas Instruments rather than National Semiconductor, as TI acquired the relevant product lines. Confirm the suffix '5.0' indicates the fixed 5V output variant. Ensure the package type matches the required through-hole TO-220-5 form factor for your specific board layout constraints.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a robust, high-input voltage buck converter is required for moderate current applications. The fixed 5V output simplifies design compared to adjustable variants. Consider the thermal performance of the TO-220 package for heat dissipation requirements in enclosed environments.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2591HV series of SIMPLE SWITCHER power converters. It is designed for high-efficiency step-down applications where input voltages significantly exceed the desired output level. The series is known for its simplicity and reliability in standard switching regulator topologies.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM2591HVT-ADJ serves as the adjustable version within the same package and family. For higher current needs, the LM2592HV series offers 2A capability. Verify pin compatibility before substituting with other buck regulators.
