Overview
The TPL9308AD is a 3-A high-current, 4-μVRMS low-noise, high-PSRR, high-accuracy linear regulator with maximum 300-mV ultra-low dropout voltage at 3-A load condition. The TPL9308AD supports both fixed output voltage ranging from 0.8 V to 3.95 V and adjustable output voltage ranging from 0.8 V to 5.2 V with an external resistor divider.
Ultra-low noise, high PSRR, and high-output-current capabilities make the TPL9308AD an ideal power supply for noise-sensitive applications, such as high-speed communication facilities, test and measurement devices, or high-definition imaging equipment. Accurate output voltage tolerance, output voltage remote sensing, excellent transient response, and adjustable soft-start control ensure the TPL9308AD is an optimal power supply for the largescale processors and digital loads, such as ASIC, FPGA, CPLD, and DSP.
The TPL9308AD provides a 20-pin QFN3.5X3.5 package with guaranteed operating junction temperature ranging (TJ) from −40°C to +125°C.
