TPS7A4901DGNR in Stock at ICGOODFIND: Powering Your Precision Designs with a Low-Noise LDO
In the world of high-performance electronics, clean and stable power is not just a requirement; it's a necessity for achieving optimal performance. For applications ranging from sensitive analog sensors and RF transceivers to precision data converters and medical instrumentation, power supply noise can be a significant bottleneck. Addressing this critical need, the TPS7A4901DGNR low-noise LDO voltage regulator stands out as a premier solution, and it is now readily available for immediate shipment from ICGOODFIND.
The TPS7A4901DGNR, manufactured by Texas Instruments, is engineered specifically to deliver exceptional power quality. Its defining characteristic is an ultra-low output noise level of 4.3 µVRMS (10 Hz to 100 kHz). This remarkably clean output ensures that the power supply does not introduce unwanted interference, which is crucial for maintaining the integrity of small-signal measurements and clear communication signals.
Beyond its quiet operation, this regulator boasts an impressively high power-supply ripple rejection (PSRR). It maintains over 70 dB of rejection at 10 kHz, effectively filtering out noise and ripple that may be present on the input voltage rail. This feature is particularly valuable in complex systems where digital and analog circuits coexist, preventing noisy digital power domains from contaminating sensitive analog supplies.
The versatility of the TPS7A4901 is another key advantage. It supports a wide input voltage range from 2.2 V to 20 V, making it compatible with a variety of power sources, including unregulated wall adapters and battery packs. It can deliver a stable output voltage from 1.2 V to 18.8 V with a maximum output current of 150 mA, suitable for powering a wide array of core components. Furthermore, its low dropout voltage maximizes efficiency, extending battery life in portable applications.
For designers, the device offers a simple design-in process with minimal external components required—often just input and output capacitors. Its thermal and overcurrent protection features also enhance the reliability of the end product.
ICGOODFIND serves as a reliable sourcing partner for such critical components, ensuring that engineers and procurement managers can secure the genuine TPS7A4901DGNR without delay, keeping their innovative projects on schedule and moving from prototype to production seamlessly.
