TPL9218-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 TPL9218 product is a 2-A high-current, 6-μV RMS low-noise, high-PSRR, and high-accuracy linear regulator with a typically 80-mV ultra-low dropout voltage in the 2-A load condition. The TPL9218 product supports 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 TPL9218 product 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 TPL9218 product an optimal power supply for largescale processors and digital loads, such as CPU, ASIC, FPGA, CPLD, and DSP.

The TPL9218 product provides a 10-pin 2.5×2.5 DFN package with guaranteed operating junction temperature ranging from −40°C to +125°C.
