TPS7B82-Q1 (ACTIVE)

Automotive 300-mA high-voltage ultra-low-Iq low-dropout (LDO) regulator

 

Description

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 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 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 well suited as a power supply for various automotive applications.
