The Texas Instruments TPS26610DDFR is a current regulator in a SOT-23-8 package (also supplied as TSOT-23-8). Its headline feature is a bipolar input range spanning -50V to 50V, which means it can regulate current on a positive supply rail, a negative rail, or across a differential bus where the common-mode voltage swings through zero.
Package and rework reality
SOT-23-8 is a small-outline package. The TSOT-23-8 variant is thinner.
The wide range means you don't need a separate high-temp variant for a motor-drive or engine-bay application — this one part spans both commercial and extended-industrial bands.
