Automotive 60V, 5-µA Iq, 100-mA, Low-Dropout Voltage Regulator with Enable and Power Good - TPS7A1601-Q1


Automotive 60V, 5-µA Iq, 100-mA, Low-Dropout Voltage Regulator with Enable and Power Good



The TPS7A16xx-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 TPS7A16xx-Q1 devices are designed for continuous or sporadic (power backup) battery-powered applications where ultralow quiescent current is critical to extending system battery life.

The TPS7A16xx-Q1 devices 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 TPS7A16xx-Q1 devices 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.
