TPS7A8400ARGRR

低压差稳压器 3A High-Accuracy 0.75% Low-Noise 4.4-++VRMS LDO Regulator 20-VQFN -40 to 125

The TPS7A84A is a low-noise, low-dropout linear regulator LDO capable of sourcing 3 A with only 180-mV of maximum dropout. The device output voltage is pin-programmable from 0.8 V to 3.95 V and adjustable from 0.8 V to 5.15 V using an external resistor divider.

The combination of low-noise, high-PSRR, and high output-current capability makes the TPS7A84A ideal to power noise-sensitive components such as those found in high-speed communications, video, medical, or test and measurement applications. The high performance of the TPS7A84A limits power-supply-generated phase noise and clock jitter, making this device ideal for powering high-performance serializer and deserializer SerDes, analog-to-digital converters ADCs, digital-to-analog converters DACs, and RF components. Specifically, RF amplifiers benefit from the high-performance and > 5-V output capability of the device.

For digital loads [such as application-specific integrated circuits ASICs, field-programmable gate arrays FPGAs, and digital signal processors DSPs] requiring low-input voltage, low-output LILO voltage operation, the exceptional accuracy 0.75% over line, load, and temperature, remote sensing, excellent transient performance, and soft-start capabilities of the TPS7A84A ensure optimal system performance.

The versatility of the TPS7A84A makes the device a component of choice for many demanding applications.
