PRODUCT OVERVIEW

What Is the TPS7A4701MRGWREP?

TPS7A4701MRGWREP 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 is part of the Enhanced Product (EP) portfolio, supporting defense, aerospace, and medical applications with controlled baseline, one assembly/test site, one fabrication site, extended product life cycle, extended product-change notification, and full product traceability[reference:1][reference:2].

The TPS7A4701MRGWREP 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]. Designed with bipolar technology primarily for high-accuracy, high-precision instrumentation applications, this device is 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][reference:6].

In addition, the TPS7A4701MRGWREP 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:7][reference:8].

Ultra-Low Noise 4 µVRMS output voltage noise (10 Hz–100 kHz) for noise-sensitive analog and RF applications[reference:9].

Enhanced Product (EP) Supports defense, aerospace, and medical applications with controlled baseline and full traceability[reference:10].

Extended Temperature Range Guaranteed operation from –55°C to +125°C for harsh environments[reference:11].

DESIGN REFERENCE

Circuit Considerations for TPS7A4701MRGWREP

Output Voltage Configuration

The TPS7A4701MRGWREP offers two output voltage configuration modes[reference:40]:

ANY-OUT™ Mode: User-programmable output voltage via PCB layout, up to 20.5 V. No external feedback resistors or feed-forward capacitors required.
Adjustable Mode: Output voltage up to 34 V using external feedback resistors.
If enable is not required, tie EN to IN for normal operation[reference:41].

PCB and Power-Supply Guidance

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

Place input and output capacitors as close as possible to the device pins to minimize parasitic inductance.
Use low-ESR ceramic capacitors for optimal stability and transient response.
Ensure adequate PCB copper area for thermal dissipation. The device is available in a high-performance 5-mm × 5-mm QFN thermal package[reference:42].
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:43].
Built-in fixed current limit and thermal shutdown provide robust protection[reference:44].
Verify the recommended PCB footprint from the official datasheet before production.
