LM2597MX-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2597MX-5.0/NOPB is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments, operating at a fixed switching frequency of 150 kHz. It provides a fixed output voltage of 5 V with a maximum output current capability of 500 mA. The device supports an input voltage range from 4.5 V to 60 V and features a low quiescent current of 5 mA. It is housed in an SOIC-8 surface-mount package and operates within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic power switch rated for 0.5 A continuous load current
Fixed internal switching frequency of 150 kHz for compact external component sizing
Built-in thermal shutdown circuitry to protect against overheating conditions

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation modules
Pre-regulators for downstream linear regulators
Efficient buck converters for battery-powered systems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix MX indicates tape-and-reel packaging versus M tube packaging when sourcing. Confirm the NOPB designation ensures compliance with RoHS standards and absence of lead. Cross-reference the manufacturer part number with distributor catalogs to ensure availability of the correct reel quantity and package variant.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring high input voltages up to 60 V with moderate output current needs. The fixed 5 V output eliminates the need for external feedback resistors compared to adjustable variants. Ensure the PCB layout accommodates the SOIC-8 footprint and adequate thermal dissipation for the expected load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2597 family of SIMPLE SWITCHER regulators, designed for efficient DC-DC conversion. It serves as a drop-in replacement for older discrete solutions or less integrated regulators. The series is known for simplifying power supply design through minimal external component requirements and robust protection features.
