Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'TV' against the official onsemi datasheet to confirm package type and temperature rating. Confirm RoHS compliance status as indicated in the product documentation. Check for availability of lead-free packages if required by project specifications. Ensure the fixed 15 V output matches the system requirement, as adjustable versions exist within the same family.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 15 V output is required from an input voltage between 4.75 V and 40 V. It is suitable for designs needing 1 A continuous current with minimal external components. Consider the TO-220-5 through-hole package for applications requiring robust thermal dissipation without complex PCB layout. Verify that the 52 kHz switching frequency aligns with EMI constraints and inductor selection guidelines.

Voltage Regulators - DC DC Switching Regulators Part Context

The LM2575TV-015 is part of the LM2575 series of SIMPLE SWITCHER regulators. This family includes fixed output voltages of 3.3 V, 5.0 V, 12 V, 15 V, and an adjustable version. The series is characterized by its ability to drive a 1.0 A load with excellent line and load regulation while minimizing external component count.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Compatible substitutes include the LM2575HVT-15 from Texas Instruments and the LM2575S-15EP from National Semiconductor. These parts share similar electrical characteristics but may differ in package dimensions or manufacturer-specific pinouts. Verify functional compatibility before substitution.
