Description

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 batteryconnected 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.
