Introduction

The TPL910A series are 1-A high-current, 4.5-μV_RMS 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.

Communication: CPU, ASIC, FPGA, CPLD, DSP High-Performance Analog: ADC, DAC, LVDS, VCO Noise-Sensitive Imaging: CMOS Sensors, Video ASICs

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 highdefinition imaging equipment. Accurate output voltage tolerance, excellent transient response, and adjustable soft-start control ensures the TPL910A series products optimal power supply for the largescale processors or digital loads, such as such as ASIC, FPGA, CPLD and DSP.
