Overview
The TPL8051Q is a series of products supporting operating with 3 V to 42 V (45-V maximum transient voltage). Operating with as low as 3 V allows the TPL8051Q to continue to work well during cold-crank and start-stop conditions.
The TPL8051Q is a series of 5-μA ultra-low quiescent lowdropout voltage linear regulators with 450-mA maximum output current capability.
With the above features, the TPL8051Q series of 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 TPL8051Q series provides adjustable output voltage options, and the TPL8051Q supports a wide range of output capacitors from 2.2 μF to 200 μF with an ESR range from 0.001 Ω to 5 Ω. Also, the TPL8051Q series integrates over-current protection and over-temperature protection.
The TPL8051Q series operates in the ambient temperature range from –40°C to +125°C.
