TPS7B82-Q1 Ultra-Low-IQ LDO Regulators

Texas Instruments TPS7B82-Q1 300mA High-Voltage Ultra-Low-I_Q Low-Dropout (LDO) Regulators are designed for automotive battery-connected applications up to 40V input voltage. The TPS7B82-Q1 is an optimal solution for powering microcontrollers and CAN/LIN transceivers in stand-by systems with a 2.7µA typical quiescent current at light load. The low quiescent current (I_Q) is essential to save power and extend the battery life in automotive battery-connected applications. The device provides integrated fault protection features such as thermal shutdown, short-circuit, and overcurrent protection. When significant dissipation is across the device, a thermally conductive package is used to enable sustained operation. The ambient temperature from –40°C to 125°C and junction temperature from –40°C to 150°C are implemented on the device. The Texas Instruments TPS7B82-Q1 devices are AEC-Q100 qualified for automotive applications.
