TPS7A470x 36-V, 1-A, 4-µV
RMS
, RF LDO Voltage Regulator
1 Features 3 Description
The TPS7A47 is a family of positive voltage (+36 V),
1
• Input Voltage Range: +3 V to +36 V
ultralow-noise (4 µV
RMS
) low-dropout linear regulators
• Output Voltage Noise:
(LDO) capable of sourcing a 1-A load.
4 µV
RMS
(10 Hz, 100 kHz)
The TPS7A4700 output voltages are user-
• Power-Supply Ripple Rejection:
programmable (up to 20.5 V) using a printed circuit
– 82 dB (100 Hz)
board (PCB) layout without the need of external
resistors or feed-forward capacitors, thus reducing
– ≥ 55 dB (10 Hz, 10 MHz)
overall component count.
• Two Output Voltage Modes:
The TPS7A4701 output voltage can be configured
– ANY-OUT™ Version (User-Programmable
with a user-programmable PCB layout (up to 20.5 V),
Output via PCB Layout):
or adjustable (up to 34 V) with external feedback
– No External Feedback Resistors or Feed-
resistors.
Forward Capacitors Required
The TPS7A47 is designed with bipolar technology
– Output Voltage Range: +1.4 V to +20.5 V
primarily for high-accuracy, high-precision
– Adjustable Version (TPS7A4701 only):
instrumentation applications where clean voltage rails
– Output Voltage Range: +1.4 V to +34 V
are critical to maximize system performance. This
feature makes the device ideal for powering
• Output Current: 1 A
operational amplifiers, analog-to-digital converters
• Dropout Voltage: 307 mV at 1 A
(ADCs), digital-to-analog converters (DACs), and
• CMOS Logic Level-Compatible Enable Pin
other high-performance analog circuitry in critical
applications such as medical, radio frequency (RF),
• Built-In Fixed Current Limit and
and test-and-measurement.
Thermal Shutdown
• Available in High-Performance Thermal Package:
In addition, the TPS7A47 is ideal for post dc-dc
converter regulation. By filtering out the output
5-mm × 5-mm QFN
voltage ripple inherent to dc-dc switching
• Operating Temperature Range:
conversions, maximum system performance is
–40°C to 125°C
ensured in sensitive instrumentation, test-and-
measurement, audio, and RF applications.
2 Applications
For applications where positive and negative low-
• Voltage-Controlled Oscillators (VCO)
noise rails are required, consider TI's TPS7A33 family
• Frequency Synthesizers
of negative high-voltage, ultralow-noise linear
regulators.
• Test and Measurement
• Instrumentation, Medical, and Audio
