TPS7B84-Q1

SBVS361 –APRIL 2020

TPS7B84-Q1 150-mA, 40-V, Adjustable, Low-Dropout Regulator

1 Features

3 Description

The TPS7B84-Q1 is a low-dropout linear regulator

designed to connect to the battery in automotive

applications. The device has an input voltage range

extending to 40 V, which allows the device to

withstand transients (such as load dump) that are

anticipated in automotive systems. With only a 20-µA

quiescent current at light loads, the device is an

optimal solution for powering always-on components

such as microcontrollers (MCUs) and controller area

network (CAN) transceivers in standby systems.

•

AEC-Q100 qualified for automotive applications:

–

Temperature grade 1: –40°C to +125°C, T_A

Junction temperature: –40°C to +150°C, T_J

•

Input voltage range: 3 V to 40 V (42 V max)

Output voltage range:

–

Adjustable output: 1.2 V to 18 V

Fixed output: 3.3 V and 5 V

•

Output current: up to 150 mA

Output voltage accuracy: ±1.5% (max)

Low dropout voltage:

The TPS7B84-Q1 has both fixed and adjustable

output types. The wide output voltage range allows

the device to generate the bias voltage for silicon

carbide (SiC) gate drivers and microphones as well

as power MCUs and processors.

–

255 mV (max) at 150 mA (V_OUT≥ 3.3 V)

•

Low quiescent current:

–

20 µA (typ) at light loads

5 µA (max) when disabled

The device has state-of-the-art transient response

that allows the output to quickly react to changes in

load or line (for example, during cold-crank

conditions). Additionally, the device has a novel

architecture that minimizes output overshoot when

recovering from dropout. During normal operation, the

device has a tight DC accuracy of ±1.5% over line,

load, and temperature.

Excellent line transient response:

–

±2% V_OUTdeviation during cold-crank

±2% V_OUTdeviation (1-V/µs V_INslew rate)

•

Stable with a 2.2-µF or larger capacitor

Package options:

The device is available in both a SOT223 package

and a small VSON package with wettable flanks that

facilitates a compact printed circuit board (PCB)

design. The low thermal resistance enables sustained

operation despite significant dissipation across the

device.

–

DRB (8-pin VSON), R_θJA: 50.8ºC/W

DCY (4-pin SOT-223), R_θJA: 85.5ºC/W

2 Applications
