About this product
LM2596HVS-12 is a 3 A step-down switching regulator in a TO-263-5 surface-mount package, listed with a 12 V output. The listed input range is 4.5 V to 53 V, with conversion efficiency up to 92%. The listing also gives an adjustable output range of 3 V to 40 V, which conflicts with the 12 V parameter, so confirm the output version before use.

Frequently asked questions
Is the output fixed at 12 V or adjustable?
The part suffix -12 and the listing parameter indicate a 12 V output, but the listing also mentions a 3 V to 40 V adjustable range. Verify the output version in the manufacturer datasheet or on the part marking before connecting a load.
What input voltage do I need?
The input must be higher than the output, and the regulator cannot boost voltage. For a 12 V output, the input must be above 12 V, and the listed input range is 4.5 V to 53 V, so choose a supply that stays within that range.
