The Texas Instruments TPS73801DCQR is a 1.0 A low-dropout linear regulator in a 6-lead SOT-223 package. Its output is adjustable from 1.21 V to 20 V and it provides low output noise with a fast transient response, remaining stable with ceramic output capacitors. Reverse-battery, reverse-current, overcurrent and thermal protection are integrated, making it a robust post-regulator or standalone supply rail.
