Description

In automotive battery-connected applications, low quiescent current (I_Q) is important to conserve energy and to extend battery lifetime. Always-on systems must have ultralow I_Q over an extended temperature range to enable sustained operation when the vehicle ignition is off.

The TPS7B81-Q1 is a low-dropout (LDO) linear regulator designed for up to 40-V V_IN applications. With only a 2.7-µA typical quiescent current at light load, the device is an optimal solution for powering microcontrollers and controller area network and local interconnect network (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 is available in several packages of varying size and thermal conductivity. The small WSON package facilitates the most compact PCB design and the TO-252 package enables sustained operation despite significant dissipation across the device. These features make the device well suited as a power supply for various battery-connected automotive applications.
