LM2575TV-012G

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575TV-012G is a monolithic integrated circuit providing all active functions for a step-down (buck) switching regulator. Manufactured by onsemi, this device features a fixed 12V output and supports up to 1A load current. It operates with a typical switching frequency of 52 kHz and accepts an input voltage range from 4.75V to 40V. The component utilizes a TO-220-5 through-hole package and is rated for a junction temperature operating range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates internal fixed-frequency oscillator and error amplifier for simplified design
• Includes built-in thermal shutdown and current limit protection circuits
• Requires minimal external components for standard buck converter topology

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power supply systems requiring step-down regulation
• On-card switching regulators for board-level voltage conversion
• Efficient linear regulator pre-regulators to reduce heat dissipation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

This specific part number is officially listed as End-of-Life (EOL) by the manufacturer. Verification of final availability through authorized distributors is required before integration into new designs. Engineers should confirm RoHS compliance status via official datasheets and review Product Change Notifications for any discontinuance timelines or last-time-buy recommendations.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output at 1A is required in a through-hole configuration. Ensure the input voltage does not exceed the 40V maximum rating. Consider the thermal performance of the TO-220-5 package under full load conditions. Verify that the 52 kHz switching frequency aligns with electromagnetic interference constraints and inductor selection requirements for the target application.

Voltage Regulators - DC DC Switching Regulators Part Context

The LM2575 series represents a family of simple, efficient step-down switching regulators designed for ease of use. This specific variant belongs to the standard voltage range lineup, distinct from high-voltage HV versions. The 'TV' suffix indicates the through-hole TO-220-5 packaging format, differentiating it from surface-mount options like D2PAK or SOIC found in other series members.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM2575T-ADJG is a manufacturer-recommended alternative within the same family, offering adjustable output voltage instead of fixed 12V. For similar fixed-output applications, the TL2575HV-12IKV from Texas Instruments serves as a comparable option, though it belongs to the high-voltage series with different electrical characteristics.
