Description

The TPL810 is a series of high-performance and lowdropout

linear regulators. The TPL810 series supports a

maximum 24-V input voltage and 180-mA output current

with a low quiescent current and high PSRR. The TPL810

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

and a 4.7-μF ceramic capacitor is recommended.

The TPL810 series has a high PSRR of 73 dB at 100

Hz. This feature makes the TPL810 series very suitable

for power-sensitive applications with high noise from the

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

current makes the TPL810 series an ideal choice for

portable devices with battery power supplies. Current-limit

and thermal overload protection circuits improve reliability

under heavy load conditions.

The TPL810 series provides fixed output voltage options

from 2.8 V to 5 V and adjustable output voltage from 1.2

V to 15 V with ±2% voltage accuracy over the operating

conditions. The TPL810 series is guaranteed over the

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