TPL8031Q-S

42-V 300-mA Wide-input Ultra-low Quiescent Current Low-Dropout

Linear Regulator

Features

Applications

Qualified for Automotive Applications

Automotive Clusters and Infotainment

Automotive Headlights and Interior Lighting

Automotive Domain Control

•

AEC-Q100 Grade 1, T_A: −40°C to +125°C

–

Junction Temperature, T_J: −40°C to +150°C

–

Input Voltage: 3 V to 42 V

Output Voltage:

Automotive BCM and Door Handler

•

Description

Fixed 5 V and 3.3 V

–

The TPL8031Q series products support operating with 3 V

to 42 V (45-V maximum transient voltage). Operating with

as low as 3 V allows the TPL8031Q to continue to work

well during cold-crank and start-stop conditions.

±2.5% Output Accuracy Over Line Regulation, Load

Regulation, and Operating Temperature Range

•

Low Current Consumption:

400-nA Shutdown Current

–

The TPL8031Q series products are 3-μA ultra-low

quiescent low dropout voltage linear regulators with 300-

mA maximum output current capability.

3-μA Typical Quiescent Current

–

300-mA Maximum Output Current

•

Low Dropout Voltage: 720 mV Maximum at 200 mA

Load Current

With the above features, the TPL8031Q series products

are the optimal solutions for powering the MCU, CAN/LIN

transceivers in the always-on applications, and the battery-

connected applications in the automotive systems.

Stable with 1-μF to 200-μF Output Capacitor with ESR

Range from 0.001 Ω to 10 Ω

•

Integrated Protection:

The TPL8031Q series provides fixed 5-V and 3.3-V output

voltage options, and the TPL8031Q supports a wide range

of output capacitors from 1 μF to 200 μF with an ESR

range from 0.001 Ω to 10 Ω. Also, the TPL8031Q series

integrated over-current protection and over-temperature

protection.

Over-Current Protection

–

Over-Temperature Protection

–

Package Options:

•

DFN3X3-8

–

EMSOP8

–

The TPL8031Q series products operate in the ambient

temperature range from −40°C to +125°C. Additionally, the

TPL8031Q series provide thermal-enhanced packages of

DFN3X3-8, EMSOP8, and SOT223-3 to enable sustained

operation despite significant dissipation across the device.
