LM2594M-3.3

Voltage Regulators - DC DC Switching Regulators Overview

The LM2594M-3.3/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a 150 kHz step-down voltage regulator. It provides a fixed 3.3 V output with a maximum current of 500 mA. The device operates within an input voltage range of 4.5 V to 40 V and supports surface-mount installation in an SOIC-8 package. It features a shutdown capability and maintains operation across a temperature range of -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic switching regulator designed for high-efficiency step-down conversion
Fixed internal feedback network ensures stable 3.3 V output without external adjustment components
Includes thermal shutdown protection to safeguard the device under overload conditions

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for digital logic circuits
Input conditioning for battery-powered systems
Pre-regulation stages for downstream linear regulators

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free compliance and RoHS adherence. Confirm the 'M' designation corresponds to the SOIC-8 surface mount package variant. Ensure the specific part number includes the fixed 3.3 V output configuration rather than adjustable or other voltage variants.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact, fixed 3.3 V supply is required at up to 500 mA. It is suitable for designs prioritizing simplicity over programmability. Consider the 150 kHz switching frequency for passive component sizing constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2594 family of SIMPLE SWITCHER converters. It shares architectural similarities with the LM2596 but offers lower current capacity. The series is widely used in general-purpose power management applications requiring reliable buck conversion.
