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 capability 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 softstart 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.
