Overview

The TPS7A43 is an 85-V, low quiescent current, low-dropout (LDO) linear regulator. The very low IQ performance makes the device an excellent choice for battery-powered or line-power applications that are expected to meet increasingly stringent standby-power standards.

The high accuracy over temperature and power-good indication make this device designed for meeting a broad range of microcontroller power requirements. The device features a selectable MID_OUT voltage pin to provide a secondary voltage to serve as a bias rail for gate drivers.

For increased robustness, the TPS7A43 also incorporates precision enable, output current limit, active discharge, and thermal shutdown protection. The operating junction temperature for this device is from –40°C to +125°C.
