Description

The TPL5080x series is a low dropout voltage regulator

with a typical dropout voltage of 320mV at 800 mA load

current.

The TPL5080x series is available in two fixed voltages, 3.3

V and 5 V. The TPL5080x series offers current limiting and

thermal shutdown.

The TPL5080x series supports a wide range of output

capacitors from 2.2 μF to 1000 μF with an ESR range

from 0.001 Ω to 5 Ω. Also, the TPL5080x series integrates

over-current protection and over-temperature protection.

The TPL5080x series provides the SOT223-3 package

with a guaranteed operating junction temperature range

(TJ) from –40°C to +125°C.
