TPS7A1633-Q1 Features Ultra-Low Quiescent Current and High Input Voltage

This post sponsored by Texas Instruments.

The TPS7A16xx-Q1 ultralow-power, low-dropout (LDO) voltage regulators, qualified for automotive applications, offer the benefits of ultra-low 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 ultra-low 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 also they can also withstand and maintain regulation during voltage transients. These features translate to simpler and more cost-effective, electrical surge-protection circuitry. Additional applications for the device are microprocessor and microcontroller systems, notebook PC and digital TV power supplies, and smoke/COs detectors.
