The TPL910A series are 1-A high-current, 4.5-μVRMS low-noise, high-PSRR, high-accuracy linear regulators with only 500-mV maximum ultra-low dropout voltage at 1-A load current. The TPL910A series support both fixed output voltage ranges from 1.2 V to 5 V and adjustable output voltage ranges from 0.8 V to 6 V with external resistor divider.

Ultra-low noise, high PSRR, and high output current capability makes the TPL910A series as the ideal power supply for noise-sensitive applications, such as high-speed communication facilities, and highdefinition imaging equipment. Accurate output voltage tolerance, excellent transient response, and adjustable soft-start control ensures the TPL910A series products optimal power supply for the largescale processors or digital loads, such as such as ASIC, FPGA, CPLD and DSP.

The TPL910A series provide small 3×3 DFN-8 package with guaranteed operating temperature ranges from –40°C to +125°C.
