LM2575N-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575N-ADJ is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments, housed in a TO-200 (DIP-16) package. It delivers up to 1A output current with an adjustable output voltage range of 1.23V to 37V. The device operates with a fixed internal switching frequency of 52kHz and supports input voltages up to 40V. It features integrated thermal shutdown and current limiting for robust protection.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated 52kHz oscillator eliminates external timing components
• Internal thermal shutdown and current limit protection circuits
• Adjustable output voltage via external feedback resistor network

Voltage Regulators - DC DC Switching Regulators Applications

• General-purpose DC/DC buck converter designs
• Pre-regulator stages for linear regulators
• Battery-powered systems requiring efficient voltage stepping

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'N' corresponds to the TO-200 DIP-16 package variant rather than standard surface mount or through-hole TO-220 options. Confirm RoHS compliance status as indicated by the NOPB designation if applicable. Ensure the supplier provides official datasheets matching the exact part number to avoid confusion with the LM2575HV series which has different input specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a through-hole DIP-16 form factor is required for high-voltage input applications up to 40V. It is suitable for designs needing adjustable output voltages between 1.23V and 37V with moderate efficiency requirements. Consider the thermal performance of the DIP-16 package for heat dissipation needs compared to smaller surface-mount alternatives.
