ADM7160AUJZ-3.3-R2 Ultra-Low Noise LDO Regulator

The ADM7160AUJZ-3.3-R2 is a high-performance, ultra-low noise, low dropout linear regulator from Analog Devices Inc., designed to deliver a fixed output voltage of 3.3V with an input voltage range from 4.5V to 5.5V. This regulator is ideal for sensitive RF or analog circuitry requiring a clean power supply, as it boasts an exceptionally low noise output, typically just 1.0 µV RMS within the 10 Hz to 100 kHz bandwidth.

With a maximum output current of 200 mA, this LDO is suitable for a variety of applications including precision instrumentation, medical devices, and high-end audio equipment. The ADM7160AUJZ-3.3-R2 features a low dropout voltage, ensuring efficient operation even when the input voltage is close to the output voltage, thereby minimizing power loss and improving overall system efficiency.

The device is designed with a high PSRR (Power Supply Rejection Ratio) of 80 dB at 10 kHz, which means it can effectively filter out power supply noise and ripple, providing a stable voltage output even under varying input voltage conditions. This characteristic is particularly important for maintaining the integrity of sensitive analog signals.

For protection and reliability, the ADM7160AUJZ-3.3-R2 includes several safety features such as over-current protection, thermal overload protection, and a shutdown function. The over-current protection safeguards the device against excessive currents, while the thermal overload protection ensures the regulator operates within safe temperature limits. The shutdown function allows the regulator to be turned off, reducing power consumption when not in use.

The compact SOT-23 package makes the ADM7160AUJZ-3.3-R2 an excellent choice for space-constrained applications. Its small footprint and low profile allow for high-density circuit board designs without sacrificing performance. Additionally, the device's robust design ensures long-term reliability and consistent performance across a wide range of operating conditions.

Overall, the ADM7160AUJZ-3.3-R2 from Analog Devices Inc. is a versatile and reliable choice for any design requiring a high-quality, low-noise power supply.
