LM2575GR-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575GR-ADJ is a step-down switching voltage regulator manufactured by TAEJIN Technology Co. It operates with a fixed internal oscillator frequency of 52 kHz and supports an adjustable output voltage range from 1.23 V to 37 V, maintaining a maximum tolerance of ±4% under line and load conditions. The device guarantees a continuous output current of 1 A and accepts a wide input voltage range. Designed for high efficiency, it requires only four external components for implementation. Key protection features include thermal shutdown and current limit capabilities.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated 52 kHz fixed-frequency internal oscillator
• Guaranteed 1 A output current capability
• Adjustable output voltage range from 1.23 V to 37 V
• Built-in thermal shutdown and current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

• General-purpose DC/DC step-down power supplies
• Pre-regulator circuits for linear regulators

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation on the component marking, as the LM2575 series is widely produced by multiple vendors including Texas Instruments and ON Semiconductor. Confirm that the specific 'GR' suffix aligns with TAEJIN's package and tape-and-reel specifications. Ensure compatibility with required external inductor and capacitor values specified in the official TAEJIN datasheet for stable operation at the target load.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple, cost-effective buck converter solution is needed for currents up to 1 A. The adjustable version offers flexibility for non-standard voltage requirements within the 1.23 V to 37 V range. Consider the 52 kHz switching frequency for balancing component size and efficiency. Verify that the input voltage range covers the application's minimum and maximum supply levels.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 family of 1-A step-down switching regulators. While originally introduced by National Semiconductor (now TI), TAEJIN Technology manufactures compatible versions. The 'ADJ' suffix denotes the adjustable output variant, distinct from fixed-voltage options like 3.3V or 5.0V. The 'GR' typically indicates the surface-mount package configuration and reel packaging.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct pin-compatible substitutes include LM2575HVS-ADJ/NOPB (Texas Instruments) and NJM2575F1-TE1 (Nisshinbo Micro Devices). Verify electrical parameters such as input voltage limits and switching frequency match before substitution.
