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 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.
