TPL9208-S中文资料2-A Output, High-PSRR, Low-Noise LDO Regulator数据手册3PEAK规格书

描述 Description

The TPL9208 series of products are 2-A high-current, 3.3-μVRMS low-noise, high-PSRR, high-accuracy linear regulators with typically 150-mV ultra-low dropout voltage at 2-A load condition. The TPL9208 series of 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 capabilities make the TPL9208 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 TPL9208 series an optimal power supply for largescale processors and digital loads, such as CPU, ASIC, FPGA, CPLD, and DSP.

The TPL9208 series of products provide 10-pin DFN2.5X2.5 and 20-pin QFN5X5 packages with guaranteed operating junction temperature ranging from −40°C to +125°C.
