LDO linear regulator is an optimal solution for powering microcontrollers

Texas Instruments TPS7B81-Q1 Low-Dropout (LDO) Linear Regulator is created for up to 40V VIN applications. With only a 2.7µA typical quiescent current at light load, the device is an excellent solution for powering microcontrollers. It can also power CAN and LIN transceivers in standby systems. The device features integrated short-circuit and overcurrent protection. The device works in ambient temperatures from –40C to +125C and with junction temperatures from –40C to +150C.

This regulator is offered in several packages of varying size and thermal conductivity. The small WSON package aids the most compact PCB design, and the TO-252 package allows sustained operation notwithstanding significant dissipation across the device. These features make the device ideal as a power supply for different battery-connected automotive applications.

The device is suitable for cluster power supply, body control modules, powering MCUs and CAN/LIN transceivers, always-on battery-connected applications, gateway applications, and remote keyless entry systems.
