产品概览
TPS7A8400RGR from TI is a 3A ultra-low-noise (4.4uVrms) LDO with 0.75% accuracy. 1.1-6.5V input. ANY-OUT programming (0.8-3.95V). 180mV max dropout at 3A. VQFN-20. Ideal for ADC/DAC/RF power.
工作原理
Low-noise LDO with internal reference and error amplifier. ANY-OUT pins program output in 50mV steps without resistors. NR/SS pin reduces noise and controls soft-start. PG flag for power monitoring. Remote sense capability.
