PRODUCT OVERVIEW

What Is the TPS7A4701RGWT?

TPS7A4701RGWT is a positive voltage (36 V), ultra-low-noise (4 µVRMS) low-dropout linear regulator (LDO) from Texas Instruments, capable of sourcing a 1-A load[reference:0]. The device operates over a –40°C to +125°C temperature range and is designed with bipolar technology primarily for high-accuracy, high-precision instrumentation applications where clean voltage rails are critical to maximize system performance[reference:1][reference:2].

The TPS7A4701RGWT output voltage can be configured with a user-programmable printed circuit board (PCB) layout (up to 20.5 V) via the ANY-OUT™ version, or adjustable (up to 34 V) with external feedback resistors[reference:3][reference:4]. 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[reference:5].

In addition, the TPS7A4701RGWT 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[reference:6].

Ultra-Low Noise 4 µVRMS output voltage noise (10 Hz–100 kHz) for noise-sensitive analog and RF applications[reference:7].

High PSRR 82 dB at 100 Hz and ≥55 dB from 10 Hz to 10 MHz for excellent power-supply ripple rejection[reference:8].

Wide Input Range 3 V to 36 V input voltage range with 1-A output current capability[reference:9][reference:10].

Circuit Considerations for TPS7A4701RGWT

Output Voltage Configuration

The TPS7A4701RGWT offers two output voltage configuration modes[reference:29]:

ANY-OUT™ Mode: User-programmable output voltage via PCB layout, up to 20.5 V. No external feedback resistors or feed-forward capacitors required[reference:30].
Adjustable Mode: Output voltage up to 34 V using external feedback resistors (TPS7A4701 only)[reference:31].
If enable is not required, tie EN to IN for normal operation[reference:32].

PCB and Power-Supply Guidance

LDO regulator performance depends on layout, bypassing, and thermal management:

Place a ≥1 µF input capacitor (10 µF recommended) from IN to GND as close to the device as possible.
Place a ≥10 µF output capacitor (47 µF recommended) from OUT to GND as close to the device as possible.
Connect a ≥10 nF capacitor (1 µF recommended) from NR to GND to minimize noise.
Connect the thermal pad to a large-area ground plane.
For post dc-dc converter regulation, the high PSRR (82 dB at 100 Hz, ≥55 dB from 10 Hz–10 MHz) effectively filters switching noise[reference:33].
Verify the recommended PCB footprint from the official datasheet before production.
