Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2597MX-3.3/NOPB

LM2597MX-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2597MX-3.3/NOPB is a SIMPLE SWITCHER® step-down voltage regulator from Texas Instruments, housed in an SOIC-8 package. It operates with a fixed switching frequency of 150 kHz and delivers a maximum output current of 0.5 A at a fixed 3.3 V output. The device supports an input voltage range of 4.5 V to 40 V and functions within a temperature range of -40°C to +125°C. Quiescent current is specified at 5 mA.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic power switch rated for 0.5 A continuous load
Fixed internal switching frequency eliminates external timing components
Built-in thermal shutdown and current limit protection mechanisms

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
Efficient buck conversion for battery-powered devices
Pre-regulator stages for linear regulators

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the MX suffix indicates cut-tape packaging rather than tube configuration. Confirm RoHS compliance status via the official datasheet. Ensure the specific revision matches design requirements as component revisions may occur without notice.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part for applications requiring a fixed 3.3 V output from higher input voltages up to 40 V. The 150 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the 0.5 A current rating meets peak load demands including transient spikes.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2597 family of SIMPLE SWITCHER regulators. It shares architectural similarities with the LM2594 but offers extended input voltage support up to 40 V. The MX variant specifically denotes surface-mount packaging optimized for automated assembly processes.
