Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2596T-3.3/NOPB

LM2596T-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2596T-3.3/NOPB is a Texas Instruments SIMPLE SWITCHER step-down voltage regulator in a TO-220-5 through-hole package. It provides a fixed 3.46V output at up to 3A load current with an input range of 4.5V to 40V. Operating at a 150 kHz switching frequency, it achieves 73% efficiency and maintains low ripple and noise of 3%. The device functions within a temperature range of -40°C to +125°C and includes internal features such as a 5mA operating supply current and shutdown capability.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated buck topology for efficient step-down conversion
Fixed 3.46V output voltage option
Internal thermal shutdown and current limiting protection

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for digital circuits
Pre-regulator stages for linear regulators
Battery-powered systems requiring voltage reduction

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB confirms lead-free and RoHS compliance. Confirm the TO-220-5 package matches the target PCB footprint. Ensure the fixed 3.46V output aligns with system requirements rather than standard 3.3V nominal values.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part for high-current applications requiring through-hole mounting. Compare against LM2596S variants if surface mount space is limited. Consider the fixed output constraint versus adjustable versions if voltage flexibility is needed.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the LM2596 family of monolithic integrated step-down converters. Designed to drive 3A loads with excellent line and load regulation. The SIMPLE SWITCHER series simplifies design by integrating the switch and control circuitry.
