TPL8031Q

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

Overview

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.

The TPL8031Q series products are 3-μA ultra-low quiescent low dropout voltage linear regulators with 300- mA maximum output current capability.

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.

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.

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.
