Description

The TPL910Q series is a 1-A high-current, 4.9-μVRMS

low-noise, 78-dB high-PSRR linear regulator with 500-mV

maximum ultra-low dropout voltage at 1-A load current.

The TPL910Q supports adjustable output voltage ranging

from 0.8 V to 5 V with an external resistor divider.

Ultra-low noise, high PSRR, and high output current

capabilities make the TPL910Q the ideal power supply

for noise-sensitive applications, such as high-speed

communication facilities, and high-definition imaging

equipment. With accurate output voltage tolerance,

excellent transient response, and adjustable soft-start

control, the TPL910Q is an optimal power supply for the

large-scale processors or digital loads, such as automotive

ECUs.

The TPL910Q provides a DFN3X3-8 package with

guaranteed operating ambient temperature ranging from

–40°C to +125°C.
