LM2596S-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2596S-5.0/NOPB is a Texas Instruments SIMPLE SWITCHER step-down voltage regulator in the LM2596 series. It operates with an input voltage range of 4.5V to 40V and provides a fixed 5.0V output at up to 3A load current. The device switches at a nominal frequency of 150kHz, enabling the use of smaller external filter components. It features ±4% output voltage tolerance and includes internal frequency compensation. The regulator is housed in a surface-mount TO-263-5 (D2PAK) package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated fixed-frequency oscillator and internal frequency compensation for simplified design
• Built-in thermal shutdown and current limit protection circuits
• External shutdown capability with low standby current consumption
• Compatible with standard off-the-shelf inductors

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial power supply systems
• Direct-in-from-battery converters
• Post-regulation switching controllers

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SX' against the requested 'S' designation, as they may denote different tape-and-reel packaging or minor manufacturing variations within the same electrical specification. Confirm RoHS compliance status via the official datasheet, as historical batches may differ. Ensure the supplier provides traceable documentation matching the Texas Instruments part number exactly to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from a wide input voltage range up to 40V. It is suitable for designs needing up to 3A continuous current with high efficiency. Consider the TO-263-5 package for adequate thermal dissipation without excessive board space. Compare against adjustable variants if flexible output voltages are needed instead of the fixed 5.0V configuration.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2596 family of monolithic integrated step-down switching regulators originally developed by National Semiconductor and now manufactured by Texas Instruments. The family includes fixed voltage options such as 3.3V, 12V, and the adjustable ADJ version. These devices are widely recognized for their simplicity, requiring only four external components to function effectively in buck converter topologies.
