TPS7A8400RGRR

具有电源正常指示功能的 3A、低输入电压、低噪声、高精度、超低压降稳压器 20-VQFN -40 to 125

The TPS7A84 is a low-noise 4.4 µVRMS, 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 5.0 V using an external resistor divider.

The combination of low-noise 4.4 µVRMS, high-PSRR, and high output current capability makes the TPS7A84 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 TPS7A84 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 5.0-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 TPS7A84 ensure optimal system performance.

The versatility of the TPS7A84 makes the device a component of choice for many demanding applications.
