Description

The TPL8031 series products support operating with 3 V to

40 V (45-V maximum transient voltage).

The TPL8031 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 TPL8031 series products are

the optimal solutions for handheld devices with battery

power supply, POS, Power Tools, and Wireless Modules.

The TPL8031 series provides fixed 5-V and 3.3-V output

voltage options, and the TPL8031 supports a wide range

of output capacitors from 1 μF to 200 μF with an ESR

range from 0.001 Ω to 5 Ω. Also, the TPL8031 series

integrates over-current protection and over-temperature

protection.

The TPL8031 series products operate in the ambient

temperature range from −40°C to +125°C.
