DESCRIPTION
The TPS7A1633-Q1, TPS7A1601-Q1, and TPS7A1650-Q1 ultralow-power, low-dropout (LDO) voltage regulators
offer the benefits of ultralow quiescent current, high input voltage, and miniaturized, high-thermal-performance
packaging.
The TPS7A1633-Q1, TPS7A1601-Q1, and TPS7A1650-Q1 are designed for continuous or sporadic (power
backup) battery-powered applications where ultralow quiescent current is critical to extending system battery life.
The TPS7A1633-Q1, TPS7A1601-Q1, and TPS7A1650-Q1 offer an enable pin (EN) compatible with standard
CMOS logic and an integrated open-drain active-high power-good output (PG) 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 TPS7A1633-Q1, TPS7A1601-Q1, and TPS7A1650-Q1 are ideal for generating a low-voltage
supply from multicell solutions ranging from high-cell-count power-tool packs to automotive applications; not only
can these devices supply a well-regulated voltage rail, but they can also withstand and maintain regulation during
voltage transients. These features translate to simpler and more cost-effective, electrical surge-protection
circuitry.
