TPS7A8500ARGRT

LDO稳压器, 可调, 1.1 V至6.5 V输入, 150 mV压降, 0.8 V至5.1 V/4 A输出, VQFN-20

The TPS7A85A is a low-noise 4.4 µVRMS, low dropout linear regulator LDO capable of sourcing 4 A with only 240 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 5.1 V using an external resistor divider.

The combination of low-noise 4.4 µVRMS, high- PSRR, and high output current capability makes the TPS7A85A 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 TPS7A85A 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 5.1-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 load and temperature, remote sensing, excellent transient performance, and soft-start capabilities of the TPS7A85A ensure optimal system performance.

The versatility of the TPS7A8500A makes the device a component of choice for many demanding applications.
