            TPS7A4701 RF LDO Voltage Regulator 
                    TI's TPS7A4701 output voltage can be configured with a user-programmable PCB layout (up to 20.5 V), or adjustable (up to 34 V) with external feedback resistors
    

Image of Texas Instruments' TPS7A4701 RF LDO Voltage Regulator Texas Instruments' TPS7A47 is designed with bipolar technology primarily for high-accuracy, high-precision instrumentation applications where clean voltage rails are critical to maximize system performance. This feature makes the device ideal for powering operational amplifiers, analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and other high-performance analog circuitry in critical applications such as medical, radio frequency (RF), and test-and-measurement.

In addition, the TPS7A47 is ideal for post-DC/DC converter regulation. By filtering out the output voltage ripple inherent to DC/DC switching conversions, maximum system performance is ensured in sensitive instrumentation, test-and-measurement, audio, and RF applications.
