LM2575D2T-5G

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575D2T-5G is a monolithic integrated circuit step-down switching regulator manufactured by onsemi. It operates as a buck converter with a fixed 5 V output and supports up to 1 A of output current. The device utilizes pulse width modulation (PWM) technology at a nominal switching frequency of 52 kHz. It accepts an input voltage range from 7 V to 40 V. The component is housed in a TO-263-5 surface-mount package and is rated for operation within a temperature range of -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'D2T' confirms the TO-263-5 surface mount package variant rather than through-hole versions. Confirm the '-5G' designation indicates the fixed 5 V output voltage and RoHS compliance status. Cross-reference the manufacturer part number with official datasheets to ensure compatibility with required input voltage ranges and thermal management specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from an input source between 7 V and 40 V. Ensure the application demands a maximum load current of 1 A or less. Verify that the PCB layout can accommodate the TO-263-5 package dimensions and that the operating environment stays within the specified -40 °C to +125 °C temperature range.
