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.
