LM2596T-5.0/LF03

Voltage Regulators - DC DC Switching Regulators Overview

The LM2596T-5.0/LF03 is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a 150 kHz step-down voltage regulator. It provides a fixed 5 V output with a maximum current capacity of 3 A. The device operates within an input voltage range of 4.5 V to 40 V and supports a shutdown feature. It utilizes a TO-220-5 through-hole package and is rated for operation between -40 °C and +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic switching regulator designed for high-efficiency buck conversion
Includes internal frequency compensation and fixed-frequency oscillator for simplified design
Features thermal shutdown and current limit protection for robust operation

Voltage Regulators - DC DC Switching Regulators Applications

Distributed power supply systems requiring step-down regulation
Pre-regulators for linear post-regulator circuits
Efficient on-card switching regulators for battery-powered applications

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix LF03 against the manufacturer datasheet to confirm lead-free status and tape-and-reel packaging specifications. Ensure the ordering part number matches the required fixed 5 V output variant. Cross-reference the TO-220-5 package dimensions with your PCB footprint requirements before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from an input voltage up to 40 V. The TO-220-5 package is suitable for through-hole mounting where higher thermal dissipation is needed compared to surface-mount options. Consider the 150 kHz switching frequency for inductor size trade-offs.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2596 family of SIMPLE SWITCHER converters, which are widely used for efficient DC-DC step-down applications. The 'T' indicates a through-hole package, while the '-5.0' specifies the fixed 5 V output version. The LM2596 series is known for reducing design time and component count in power supply architectures.
