TPS7B85-Q1 150-mA, 40-V, Low-Dropout Regulator

With Power-Good and Integrated Voltage Monitoring

1 Features

3 Description

•

AEC-Q100 qualified for automotive applications:

The TPS7B85-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 an 18-

µA quiescent current, the device is an optimal solution

for powering always-on components such as

microcontrollers (MCUs) and controller area network

(CAN) transceivers in standby systems.

– 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: 3.3 V and 5 V (fixed)

Output current: up to 150 mA

Output voltage accuracy: ±0.75% (max)

Low dropout voltage:

– 225 mV (max) at 150 mA (V_OUT≥ 3.3 V)

Low quiescent current:

•

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 ±0.75% over line,

load, and temperature.

– 18 µA (typ)

– 4 µA (max) when disabled

Excellent line transient response:

– ±2% V_OUTdeviation during cold-crank

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

Integrated voltage detection

Power-good with adjustable threshold and

programmable delay period

Stable with a 2.2-µF or larger capacitor

Functional Safety-Capable

– Documentation available to aid functional safety

system design

•

The TPS7B85-Q1 is equipped with power-good and

integrated voltage monitoring. The power-good delay

and voltage threshold can be adjusted by external

components. The integrated voltage detector can be

used to monitor the input voltage and alert

downstream components (such as MCUs) when the

battery voltage begins to fall.

•

Package: 10-pin VSON with thermal pad

– Low thermal resistance (R_θJA): 50.3°C/W

The device is available in a small VSON package that

facilitates a compact printed circuit board (PCB)

design. The low thermal resistance enables sustained

operation despite significant dissipation across the

device.

2 Applications

•

Reconfigurable instrument clusters

Body control modules (BCM)

Always-on battery-connected applications:

– Automotive gateways
