SLVSDQ0I – SEPTEMBER 2017 – REVISED AUGUST 2021

TPS7B82-Q1 Automotive 300-mA, High-Voltage, Ultra-Low-I_QLow-Dropout Regulator

1 Features

3 Description

•

AEC-Q100 qualified for automotive applications:

– Temperature grade 1: –40°C ≤ T_A≤ 125°C

– Temperature grade 0: –40°C ≤ T_A≤ 150°C

Extended junction temperature range:

– Grade 1: –40°C ≤ T_J≤ 150°C

– Grade 0: –40°C ≤ T_J≤ 165°C

Low quiescent current I_Q:

– 300-nA shutdown I_Q

– 2.7 µA typical at light loads

– 5 µA maximum at light loads

3-V to 40-V wide V_INinput voltage range with up to

45-V transient

In automotive battery-connected applications, low

quiescent current (I_Q) is important to save power and

extend battery lifetime. Ultra-low I_Qmust 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 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 and

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.

•

Maximum output current: 300 mA

2% output-voltage accuracy

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.

Maximum dropout voltage: 700 mV at 200-mA load

current for fixed 5-V output version

Stable with low-ESR (0.001-Ω to 5-Ω) ceramic

output-stability capacitor (1 µF to 200 µF)

Fixed 2.5-V, 3.3-V, and 5-V output voltage

Packages:

– 8-pin HVSSOP, R_θJA= 63.9°C/W

– 6-pin WSON, R_θJA= 72.8°C/W

– 5-pin TO-252, R_θJA= 31.1°C/W

– 14-pin HTSSOP, R_θJA= 52.0°C/W
