The Texas Instruments TPS7A4501KTTR is a 1.5 A adjustable low-dropout regulator supplied in a TO-263 package. It provides ±1% output accuracy, an output range from 1.21 V to 20 V and an enable pin for sequencing. Low dropout and integrated overcurrent and thermal protection make it suitable for point-of-load and post-regulation duties in industrial and battery-powered systems.
