Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2594N-3.3/NOPB

LM2594N-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2594N-3.3/NOPB is a Texas Instruments SIMPLE SWITCHER power converter featuring a fixed 3.3V output and 0.5A maximum current capability. It operates as a step-down voltage regulator with a switching frequency of 150 kHz. The device supports an input voltage range from 4.5V to 40V. It utilizes an 8-pin DIP package for through-hole mounting. The operational temperature range spans from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic buck converter topology
Fixed 3.3V output voltage configuration
Through-hole DIP packaging for board integration

Voltage Regulators - DC DC Switching Regulators Applications

General-purpose DC-DC step-down conversion
Pre-regulation for linear regulators
Battery-powered systems requiring 3.3V rails

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free composition and RoHS compliance. Confirm the 'N' designation corresponds to the PDIP-8 package variant rather than surface-mount options. Ensure the fixed 3.3V output matches the target circuit requirements, as adjustable variants exist within the same series.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V output is required without external feedback resistors. The 0.5A current limit suits low-power applications. Consider the 150kHz frequency for balancing efficiency and passive component size. The through-hole package is suitable for prototyping or high-reliability manual assembly environments.

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 (0.5A vs 3A). The fixed voltage version simplifies design by eliminating external resistor networks needed for adjustable outputs.
