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), digitalto-
analog converters (DACs), and RF components.
Specifically, RF amplifiers benefit from the highperformance
and 5.1-V output capability of the
device. TPS7A8500ARGRR TPS7A8500ARGRT资料下载
