TPS7B82-Q1 (ACTIVE)

300mA High-Voltage Ultra-Low-Iq Low-Dropout (LDO) Regulator

300mA High-Voltage Ultra-Low-Iq Low-Dropout (LDO) Regulator - TPS7B82-Q1
 

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 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 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.
