描述 Description

The TPL910 series products are 1-A high-current, 24-μVRMS

low-noise, high-PSRR, high-accuracy linear regulators with only

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

The TPL910 series products support both fixed output voltage

ranges from 0.8 V to 5 V and adjustable output voltage ranges

from 0.8 V to 5.2 V with external resistor divider.

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

makes the TPL910 series products ideal power supply for noisesensitive

applications, such as high-speed communication

facilities, test and measurement devices, or high-definition

imaging equipment. Accurate output voltage tolerance, output

remote sensing, excellent transient response, and adjustable

soft-start control ensures the TPL910 series products optimal

power supply for the large-scale processors or digital loads,

such as ASIC, FPGA, CPLD and DSP.

The TPL910 series products provide 3×3 DFN-8 package with

guaranteed operating junction temperature range (TJ) from -

40°C to +125°C.
