Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'T' indicates the TO-220 through-hole package variant. Confirm the '-5.0' designation specifies the fixed 5 V output version. Ensure compatibility with lead-free manufacturing processes if RoHS compliance is required. Cross-reference the datasheet for specific pinout configurations and thermal pad requirements during integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from a high-voltage source up to 60 V. The TO-220 package offers superior thermal dissipation compared to surface-mount options for higher current loads. Consider the 150 kHz frequency for balancing efficiency and passive component size against lower-frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2593HV series of SIMPLE SWITCHER regulators. It shares architectural similarities with the LM2590 and LM2596 families but is optimized for higher input voltages. The device simplifies design by integrating the control circuitry and power switch into a single IC, reducing the bill of materials for buck converter designs.
