TPS746-Q1 - Texas Instruments

TPS746-Q1 Automotive 1-A LDO

The TPS746-Q1 is a 1-A, ultra-low-dropout regulator (LDO) with power-good functionality. This device is available in a small 6-pin, 2-mm × 2-mm WSON package and a small 8-pin, 3-mm × 3-mm VSON package with wettable flanks to facilitate optical inspection. The TPS746-Q1 consumes low quiescent current and provides fast line and load transient performance. Th.
