Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2598T-12/NOPB

LM2598T-12/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2598T-12/NOPB is a SIMPLE SWITCHER step-down switching regulator manufactured by Texas Instruments. It operates with an input voltage range of 4.5V to 40V and provides a fixed output voltage of 12V at up to 1A output current. The device utilizes a buck topology with a standard switching frequency of 150 kHz. It features a low quiescent supply current of 5 mA and supports operation across a temperature range from -40°C to +125°C. The component is housed in a TO-220-7 package designed for through-hole mounting.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic switching regulator with built-in fixed-frequency oscillator
Includes internal frequency-compensated error amplifier and current-limited power transistor
Provides thermal shutdown protection for robust operation under fault conditions

Voltage Regulators - DC DC Switching Regulators Applications

Distributed power distribution systems
On-card regulation modules
Standard 12V batteries or other available bus supplies conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor. Confirm the suffix NOPB indicates lead-free and RoHS compliance. Ensure the package type matches the required TO-220-7 through-hole footprint for your specific board layout constraints.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 12V output is required from a higher voltage rail up to 40V. The 1A current capability suits moderate load applications. Consider the TO-220-7 package for easier thermal management compared to smaller surface-mount options if space permits.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2598 series of SIMPLE SWITCHER regulators. It is distinct from the LM2596 (3A) and LM2594 (0.5A) variants. The 'T' suffix denotes the TO-220-7 through-hole package, while '12' specifies the fixed 12V output version.
