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-supplygenerated
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. TPS7A8400ARGRR TPS7A8400ARGRT资料下载
