LM2598T-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2598T-5.0/NOPB 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 of 1 A. The device supports an input voltage range from 4.5 V to 40 V and operates within a temperature range of -40 °C to +125 °C. Packaged in a TO-220-7 through-hole format, it integrates a monolithic switching regulator for efficient DC-DC conversion.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated monolithic switching regulator simplifies design
• Fixed internal frequency reduces external component count
• Built-in thermal shutdown protects against overheating

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power supply systems
• Direct board regulation from bus supplies
• Efficient pre-regulator circuits before linear regulators

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status according to the manufacturer's latest environmental declarations. Confirm the package type matches the required TO-220-7 footprint for your PCB layout. Ensure the fixed 5 V output variant aligns with system voltage requirements rather than adjustable versions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output at up to 1 A is required from an input between 4.5 V and 40 V. The through-hole TO-220-7 package suits applications needing robust thermal dissipation without complex heatsinking. Consider the 150 kHz switching frequency for balancing component size and efficiency needs.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the SIMPLE SWITCHER family of step-down regulators. It shares architectural similarities with the LM2596 and LM2599 series but offers distinct current ratings and package options. The LM2598T-5.0/NOPB specifically targets applications requiring moderate current levels with high input voltage tolerance in a through-hole configuration.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2598T-5.0/NOPB serves as a direct replacement for older National Semiconductor LM2598T-5.0 variants. Cross-reference with LM2596T-5.0 if lower current (0.5A) suffices, or LM2599T-5.0 for higher current (3A) requirements, ensuring package and pinout compatibility.
