3 Description

In automotive battery-connected applications, low

quiescent current (IQ) is important to save power and

extend battery lifetime. Ultra-low IQ must be included

for always-on systems.

The TPS7B82-Q1 is a low-dropout linear regulator

designed to operate with a wide input-voltage range

from 3V to 40V (45V load dump protection). Operation

down to 3V allows the TPS7B82-Q1 to continue

operating during cold-crank and start and stop

conditions. With only 2.7μA typical quiescent current

at light load, this device is an optimum design

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 designed as a power

supply for various automotive applications.
