Description

The TPL8035Q series supports operating with 3 V to 42

V (45-V maximum transient voltage). Operating with as

low as 3 V allows the TPL8035Q to continue to work well

during cold-crank and start-stop conditions.

The TPL8035Q products are 3-μA ultra-low quiescent low

dropout voltage linear regulators with 300-mA maximum

output current capability.

With the above features, the TPL8035Q 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 TPL8035Q series provides fixed 5-V and 3.3-V output

voltage options. What's more, the TPL8035Q 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

TPL8035Q series integrates over-current protection and

over-temperature protection.

The TPL8035Q series operates in the ambient

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

TPL8035Q series provides a thermal-enhanced package

of DFN3X3-8 to enable sustained operation despite

significant dissipation.
