TPL8034Q

42-V/300-mA Wide-Input Ultra-low Quiescent Current Low-Dropout Linear Regulator with Power-Good Indicator

概述

The TPL8034Q series supports operating with 3 V to 42 V (45-V maximum transient voltage). Operating with as low as 3 V allows the TPL8034Q to work well during cold-crank and start-stop conditions.

The TPL8034Q products are 3-μA ultra-low quiescent low dropout voltage linear regulators with 300-mA maximum output current capability.

The TPL8034Q series integrates an open-drain output power good indicator. The power-good delay time is adjusted with an external capacitor.

With the above features, the TPL8034Q products are the optimal solutions for powering the MCU, CAN/LIN transceivers in the always-on applications, and the batteryconnected applications in the automotive systems.

The TPL8034Q series provides fixed 5-V and 3.3-V output voltage options. What's more, the TPL8034Q supports a wide range of output capacitors from 1 μF to 200 μF with an ESR range from 0.001 Ω to 10 Ω. The TPL8034Q series integrates over-current protection and over-temperature protection.

The TPL8034Q series operates in the ambient temperature range from −40°C to +125°C. Additionally, the TPL8034Q series provides a thermal-enhanced EMSOP8 package to enable sustained operation despite significant dissipation.
