In automotive battery-connected applications, low quiescent current
(IQ) is important to save power and extend battery lifetime. It is
especially necessary to have ultralow IQ for always-on systems.
The TPS7B82-Q1 is a low-dropout linear regulator designed for up to 40-V
VIN applications. With only 2.7-µA typical quiescent current at light load,
it is an optimal solution for powering microcontrollers and CAN/LIN transceivers in standyby
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 well
suited as a power supply for various automotive applications.
