In automotive battery-connected applications, low quiescent current (I Q) is important to save power and extend battery lifetime. Ultra-low I Q must be included for always-on systems.

The TPS7B82-Q1 is a low-dropout linear regulator designed to operate with a wide input-voltage range from 3 V to 40 V (45-V load dump protection). Operation down to 3 V allows the TPS7B82-Q1 to continue operating during cold-crank and start and stop conditions. With only 2.7-µA typical quiescent current at light load, this device is an optimal solution for powering microcontrollers (MCUs) and CAN/LIN transceivers in standby systems.

The device features integrated short-circuit and overcurrent protection. This device operates in ambient temperatures from –40°C to +125°C and with junction temperatures from –40°C to +150°C. Additionally, this device uses a thermally conductive package to enable sustained operation despite significant dissipation across the device. Because of these features, the device is designed as a power supply for various automotive applications.
