TPS7A5401QRGRRQ1

The TPS7A54-Q1 device 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 adjustable from 0.8 V to
5.1 V using an external resistor divider.
The combination of low-noise (4.4 µVRMS), highPSRR, and high output current capability makes the
TPS7A54-Q1 ideal to power noise-sensitive
components such as those found in radar power and
infotainment applications. The high performance of
this device limits power-supply-generated phase
noise and clock jitter, making this device ideal for
powering RF amplifiers, radar sensors, and chipsets.
Specifically, RF amplifiers benefit from the highperformance 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 (1% over
load and temperature), remote sensing, excellent
transient performance, and soft-start capabilities of
the TPS7A54-Q1 provides optimal system
performance.
The versatility of the TPS7A54-Q1 makes the device
a component of choice for many demanding
applications.
