The TPL910A series products are 1-A high-current,4.5-μVRMS low-noise, high-PSRR, high-accuracy linearregulators with only 500-mV maximum ultra-low dropoutvoltage at 1-A load current. The TPL910A series supportsadjustable output voltage ranging from 0.8 V to 6 V with anexternal resistor divider.Ultra-low noise, high PSRR, and high output currentcapability make the TPL910A series the ideal powersupply for noise-sensitive applications, such as highspeed communication facilities, and high-definition imagingequipment. Accurate output voltage tolerance, excellenttransient response, and adjustable soft-start control ensurethe TPL910A series products optimal power supply forlarge-scale processors or digital loads, such as ASIC,FPGA, CPLD, and DSP.The TPL910A series products provide a small DFN3X3-8package with guaranteed operating temperature rangingfrom –40°C to +125°C.
