LM2575TV-012

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575TV-012G is a monolithic integrated circuit step-down switching regulator from the LM2575 series, manufactured by onsemi. It operates as a fixed-output buck converter providing a stable 12V output at up to 1A load current. The device accepts an input voltage range of 4.75V to 40V and utilizes a fixed 52kHz switching frequency. Designed for through-hole mounting, it is housed in a TO-220-5 package with formed leads. The component supports an operating junction temperature range from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates all active functions required for a simple step-down (buck) switching regulator design
• Provides fixed 12V output with excellent line and load regulation capabilities
• Operates with a fixed internal switching frequency to minimize external component requirements

Voltage Regulators - DC DC Switching Regulators Applications

• Design of efficient DC-to-DC step-down converters
• Pre-regulator circuits for downstream linear regulators
• Direct regulation from bus voltages exceeding 12V

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'G' in the part number LM2575TV-012G against official datasheets to confirm RoHS compliance status. Confirm that the TO-220-5 package variant matches the intended mechanical footprint. Check for End-of-Life notifications or Product Change Notices regarding manufacturing site transfers or material updates before finalizing procurement plans.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required from an input voltage between 4.75V and 40V. Ensure the application demands a maximum continuous load current of 1A. Verify that the thermal management strategy accommodates the TO-220-5 package's heat dissipation characteristics within the specified -40°C to +125°C operating temperature range.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 family of monolithic integrated circuits designed for easy implementation of buck converters. The 'TV' designation indicates the TO-220-5 through-hole package, while the '-012' suffix specifies the fixed 12V output version. The series is characterized by its simplicity, requiring minimal external components for operation.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2575T-ADJG is listed as a manufacturer-recommended alternative, though it offers adjustable output rather than fixed 12V. TL2575HV-12IKV from Texas Instruments is identified as a similar device. Verify pinout compatibility and electrical specifications before substitution.
