LM2575D2T-012G

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575D2T-012G is a monolithic integrated circuit from the LM2575 series, functioning as a step-down switching regulator. It provides a fixed 12V output with a maximum load current of 1A. The device operates within an input voltage range of 4.75V to 40V and utilizes a buck topology at a typical switching frequency of 52kHz. Designed for surface-mount installation, it is housed in a TO-263 package. The component supports an operating junction temperature range from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a 1A power switch for efficient step-down conversion
Includes internal oscillator for fixed frequency operation
Features thermal shutdown and current limiting protection

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation modules
Pre-regulators for linear regulators
Efficient DC/DC converters

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'D2T' confirms the surface-mount TO-263 package variant rather than the through-hole version. Confirm RoHS compliance status via the manufacturer's latest material declaration. Check for End-of-Life notifications or Product Change Notices that may affect long-term availability. Ensure the fixed 12V output matches the design requirement, as adjustable variants exist within the same family.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 12V output is required with up to 1A load capacity in a surface-mount form factor. Compare against the adjustable LM2575-ADJ if variable output is needed. Consider the TO-263 package for thermal performance relative to smaller SOT packages. Verify input voltage ranges do not exceed the 40V maximum rating under all operating conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2575 family of simple-to-use step-down switching regulators. The family includes both fixed voltage outputs (e.g., 3.3V, 5V, 12V) and an adjustable version. The LM2575D2T-012G specifically denotes the surface-mount TO-263 package variant with a fixed 12V output, distinguishing it from the through-hole TO-220 versions.
