LM2595SX-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2595SX-ADJ is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments. It operates with an input voltage range of 4.5 V to 40 V and provides an adjustable output voltage between 1.2 V and 37 V. The device delivers up to 1 A of output current at a fixed switching frequency of 150 kHz. It utilizes a TO-263 (D2PAK) surface-mount package with five pins. The component functions within a junction temperature range of -40°C to +125°C and features a typical quiescent current of 5 mA.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SX' indicates the D2PAK-5 package variant when sourcing. Confirm the 'ADJ' designation ensures adjustable output functionality rather than fixed voltage options. Ensure compliance with RoHS directives as indicated by the NOPB suffix if required for your assembly process. Cross-reference datasheet revision dates to confirm pinout consistency.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an input voltage up to 40 V must be stepped down to a variable lower voltage level. It is suitable for designs requiring 1 A continuous load current with minimal external components. Consider the thermal performance of the TO-263 package for heat dissipation requirements in enclosed environments.
