TPS7B86-Q1

SBVS362 –JUNE 2020

TPS7B86-Q1 500-mA, 40-V, Low-Dropout Regulator

With Power-Good

1 Features

3 Description

The TPS7B86-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 dumps) 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

•

Maximum output current: 500 mA

Output voltage accuracy: ±1% (max)

Low dropout voltage:

The device has a 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% over line,

load, and temperature.

–

500 mV (max) at 450 mA (V_OUT≥ 3.3 V)

•

Low quiescent current:

–

20 µA (typ) at light loads

5 µA (max) when disabled

Excellent line transient response:

The device is equipped with a power-good output to

indicate when the output voltage is close to its final

value. The power-good delay can be adjusted by

external components, thus allowing the delay time to

be configured for a specific system.

–

±2% V_OUTdeviation during cold-crank

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

•

Dropout voltage: 555 mV (max) at V_OUT≥ 3.3 V

Power-good with programmable delay period

Stable with a 2.2-µF or larger capacitor

Package options:

The device is available in thermally conductive

packaging to allow the device to efficiently transfer

heat to the circuit board.

–

3-pin TO-252 package: (R_θJA): 29.7°C/W

8-pin SO-8 package: (R_θJA): 41.8°C/W
