描述 Description

The TPL730 series is a high-performance and low-dropout

linear regulator. The TPL730 series supports a maximum

300-mA output current with a low-quiescent current and

high PSRR. The TPL730 series of products is stable with

ceramic output capacitors from 2.2 μF to 10 μF.

The TPL730 series of products has a high PSRR with 60

dB at 1 kHz. This feature makes the TPL730 series very

suitable for power-sensitive applications with high noise

from the previous stage power supply. A quiescent current

of as low as 49 μA and an only 20-nA shutdown current

make the TPL730 series an ideal choice for portable

devices with a battery power supply. The current limit

foldback and thermal overload protection circuits improve

reliability under heavy load conditions.

The TPL730 series provides several output voltage version

options including the fixed version and the adjustable

version with ±2% output voltage accuracy over operating

conditions. The TPL730 series is guaranteed over the

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