The TPS7A4700 output voltages are user-• Power-Supply Ripple Rejection: programmable (upto 20.5 V) usinga 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
witha user-programmable PCB layout (upto 20.5 V),Output via PCB Layout): or adjustable (upto 34 V) with external feedback– No External Feedback Resistorsor Feed- resistors.Forward Capacitors Required
The TPS7A47is designed with bipolar technology– Output Voltage Range: +1.4Vto +20.5V primarily for high-accuracy, high-precision– Adjustable Version (TPS7A4701 only): instrumentation applications where clean voltage rails Output Voltage Range: +1.4Vto +34V are critical to maximize system performance. This
feature makes the device ideal for powering• Output Current:1A operational amplifiers, analog-to-digital converters• Dropout Voltage: 307 mVat1A (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 Availablein High-Performance Thermal Package: In addition, the TPS7A47is ideal for post dc-dc
converter regulation. By filtering out the output5-mm× 5-mm QFN
voltage ripple inherent to dc-dc switching• Operating Temperature Range: conversions, maximum system performance is–40°Cto 125°C ensured in sensitive instrumentation, test-and-
measurement, audio, and RF applications.
