Description for the TPS7A47

The TPS7A47 is a family of positive voltage (+36 V), ultralow-noise (4 µVRMS) low-dropout linear regulators (LDO) capable of sourcing a 1-A load.

The TPS7A4700 output voltages are user-programmable (up to 20.5 V) using a printed circuit board (PCB) layout without the need of external resistors or feed-forward capacitors, thus reducing overall component count.

The 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.

The 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.

For applications where positive and negative low-noise rails are required, consider TI’s TPS7A33 family of negative high-voltage, ultralow-noise linear regulators.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
