LM2595T-12/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2595T-12/NOPB is a SIMPLE SWITCHER power converter functioning as a 150 kHz step-down voltage regulator. It provides a fixed 12 V output with a maximum current of 1 A. The device accepts an input voltage range from 4.5 V to 40 V. It utilizes a TO-220-7 through-hole package and operates within 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 12 V output without external adjustment components
• Built-in frequency compensation simplifies external component selection and layout requirements

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power supply architectures requiring buck conversion
• Pre-regulator stages for linear post-regulators
• Battery-powered systems needing efficient voltage reduction

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free status and RoHS compliance per Texas Instruments documentation. Confirm the TO-220-7 package variant matches the required thermal and mechanical constraints for the target application environment before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12 V output at 1 A is required from a 4.5 V to 40 V input source. The TO-220-7 package suits applications prioritizing thermal dissipation over board space. Ensure the design accounts for the 150 kHz switching frequency for inductor and capacitor selection.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2595 series of SIMPLE SWITCHER regulators, which are known for reducing design complexity. Unlike the LM2596 (3 A) or LM2594 (0.5 A), the LM2595 bridges the gap with a 1 A capability. The T-12 designation specifies the fixed 12 V output version in the through-hole TO-220 form factor.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2595T-12 is the predecessor part number. LM2595SX-12/NOPB offers the same electrical specifications but uses a surface-mount TO-263-5 package instead of the through-hole TO-220-7 configuration.
