8.1 Overview

The TPS7A25 is an 18-V, low quiescent current, low-dropout (LDO) linear regulator. The low IQ performance makes the TPS7A25 an excellent choice for battery-powered or line-power applications that are expected to meet increasingly stringent standby-power standards.

The 1% accuracy over temperature and power-good indication make this device an excellent choice for meeting a wide range of microcontroller power requirements. Additionally, the TPS7A25 has an internal soft-start to minimize inrush current into the output capacitance.

For increased reliability, the TPS7A25 also incorporates overcurrent, overshoot pulldown, and thermal shutdown protection. The operating junction temperature is –40°C to +125°C, and adds margin for applications concerned with higher working ambient temperatures.

The TPS7A25 is available in a thermally enhanced WSON package.
