The TPS7A1601DGNT is an ultralow power low-dropout (LDO) Voltage Regulator offers the benefits of ultra-low quiescent current, high input voltage. It is designed for continuous or sporadic battery-powered applications where ultralow quiescent current is critical to extending system battery life. It also offers an enable pin compatible with standard CMOS logic and an integrated open drain active-high power good output with a user-programmable delay. These pins are intended for use in microcontroller-based, battery-powered applications where power-rail sequencing is required. In addition, the device is ideal for generating a low-voltage supply from multi-cell solutions ranging from high cell-count power-tool packs to automotive applications, not only can this device supply a well-regulated voltage rail, but it can also withstand and maintain regulation during voltage transients. These features translate to simpler and more cost-effective, electrical surge-protection circuitry.
