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.
