TPL9308-S Series 3-A Output, High-PSRR Low-Noise LDO Regulator
■The TPL9308 series products are 3-A high-current, 6-μVRMS low-noise, high-PSRR, high-accuracy linear regulators with maximum 300-mV ultra-low dropout voltage at 3-A load condition. The TPL9308 series products support 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 external resistor dividers.
■Ultra-low noise, high-PSRR, and high-output-current capability makes the TPL9308 series 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 flexible soft-start control ensure the TPL9308 series an optimal power supply for large-scale processors and digital loads, such as CPU, ASIC, FPGA, CPLD, and DSP.
■The TPL9308 series products provide a 20-pin 3.5×3.5 QFN packages with guaranteed operating junction temperature ranging from −40°C to +125°C.
