Description

The TPL820 is a series of high-performance and lowdropout linear regulators. The TPL820 series supports a

maximum 42-V input voltage and a 180-mA output current

with low quiescent current and high PSRR. The TPL820

series is stable with a 2.2-μF to 22-μF output capacitor,

and a 4.7-μF ceramic capacitor is recommended.

The TPL820 series has a high PSRR with 73 dB at 100

Hz. This feature makes the TPL820 series very suitable

for power-sensitive applications with high noise from the

previous stage power supply. A 2-μA ultra-low quiescent

current makes the TPL820 series ideal for portable devices

with a battery power supply. Current-limit and thermal

overload protection circuits improve reliability under heavy

load conditions.

The TPL820 series provides fixed output voltage options

from 3.0 V to 5 V with ±2% voltage accuracy over

operating conditions. The TPL820 series is guaranteed

over the junction temperature range from ?40°C to

+125°C.
