The TPS7A85 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 5.0 V using an external
resistor divider.
The combination of low-noise (4.4 μVRMS), high-
PSRR, and high output current capability makes the
TPS7A85 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 TPS7A85
limits power-supply-generated phase noise and clock
jitter, making this device ideal for powering highperformance
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. TPS7A8500RGRR
