LM2575TV-ADJ Equivalent & Substitute Parts

Part Overview

The LM2575TV-ADJ is a buck switching regulator IC from onsemi, designed for step-down voltage conversion with positive adjustable output. This device delivers 1A output current across an input voltage range of 4.75V to 40V, with adjustable output voltage from 1.23V to 37V. The part operates at a switching frequency of 52kHz and is housed in a TO-220-5 through-hole package.

The LM2575TV-ADJ is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this regulator.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LM2575TV-ADJ are identified based on strict electrical and mechanical parameter alignment. The critical parameters determining substitution eligibility are:

• Function: Step-Down (Buck) topology
• Output Configuration: Positive adjustable output
• Number of Outputs: Single output
• Output Voltage Range: Minimum 1.23V, maximum output voltage ≥37V
• Current Rating: 1A output capability
• Switching Frequency: 52kHz
• Package: TO-220-5 through-hole form factor
• Operating Temperature Range: -40°C to 125°C

Substitute parts must maintain compatibility across these parameters to ensure functional equivalence in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The LM2575TV-ADJ is obsolete, making LM2575TV-ADJG and TL2575HV-ADJIKV the primary alternatives for ongoing applications.

LM2575TV-ADJG is a direct onsemi replacement with identical electrical specifications and active product status. This part maintains full parameter compatibility with the original LM2575TV-ADJ while offering ROHS3 compliance and improved supply availability.

TL2575HV-ADJIKV from Texas Instruments provides functional equivalence with extended input and output voltage ranges (60V maximum input, 57V maximum output versus 40V and 37V respectively). This part is suitable for applications requiring higher voltage headroom while maintaining the same 1A output current, 52kHz switching frequency, and TO-220-5 package form factor. Both substitute parts carry ROHS3 compliance status.

Frequently Asked Questions (FAQ)

Q: Can LM2575TV-ADJG be used as a direct replacement for LM2575TV-ADJ?

A: Yes. LM2575TV-ADJG maintains identical electrical and mechanical specifications, including input voltage range (4.75V to 40V), output voltage range (1.23V to 37V), 1A output current, 52kHz switching frequency, and TO-220-5 package. The primary difference is product status (active versus obsolete) and RoHS compliance.

Q: What is the key difference between LM2575TV-ADJG and TL2575HV-ADJIKV?

A: Both parts share the same core functionality and package. TL2575HV-ADJIKV extends the maximum input voltage to 60V and maximum output voltage to 57V, compared to 40V and 37V for LM2575TV-ADJG. Applications operating within the original 40V/37V limits can use either part interchangeably.

Q: Are all substitute parts pin-compatible with the original LM2575TV-ADJ?

A: All listed substitutes use the TO-220-5 through-hole package with identical pin configuration, ensuring mechanical and electrical compatibility in existing PCB designs.

Q: Do the substitute parts require circuit modifications?

A: No circuit modifications are required when substituting within the specified voltage and current parameters. The adjustable output voltage range and feedback network design remain consistent across all listed parts.

Q: What compliance certifications apply to the substitute parts?

A: Both LM2575TV-ADJG and TL2575HV-ADJIKV are ROHS3 compliant and REACH unaffected, with EAR99 export classification.
