TPL910A数据手册3PEAK中文资料规格书

描述 Description

The TPL910A series are 1-A high-current, 4.5- μVRMS low-noise, high-PSRR, high-accuracy linear regulators with only 500-mV maximum ultra-low dropout voltage at 1-A load current. The TPL910A series support both fixed output voltage ranges from 1.2 V to 5 V and adjustable output voltage ranges from 0.8 V to 6 V with external resistor divider.

Ultra-low noise, high PSRR, and high output current capability makes the TPL910A series as the ideal power supply for noise-sensitive applications, such as high-speed communication facilities, and high-definition imaging equipment. Accurate output voltage tolerance, excellent transient response, and adjustable soft-start control ensures the TPL910A series products optimal power supply for the large-scale processors or digital loads, such as such as ASIC, FPGA, CPLD and DSP.

The TPL910A series provide small 3×3 DFN-8 package with guaranteed operating temperature ranges from –40°C to +125°C.
