Analog Devices Inc. ADM7160ACPZN1.8-R7 Ultra-Low Noise LDO

The ADM7160ACPZN1.8-R7 is a high-performance, ultra-low noise, low dropout linear regulator designed by Analog Devices Inc., a leader in high-performance analog technology. This regulator is specifically engineered to meet the stringent power supply requirements of sensitive RF and analog circuitry in a variety of applications, including wireless communication systems, medical devices, and precision instrumentation.

With a fixed output voltage of 1.8V, the ADM7160 is capable of delivering up to 200 mA of output current. What sets this LDO apart is its exceptionally low output noise of just 1.6 µV RMS over a 10 Hz to 100 kHz bandwidth, making it an ideal choice for applications that are sensitive to power supply noise. Additionally, the device features a low dropout voltage, ensuring efficient operation even when the input-to-output differential is minimal.

The ADM7160ACPZN1.8-R7 comes in a compact 6-lead TSOT package, optimized for space-constrained applications. It offers a high power supply rejection ratio (PSRR) of 80 dB up to 10 kHz, which helps to suppress variations in the input voltage and maintain a stable output. The device also includes several safety features such as over-current protection and thermal overload protection, ensuring reliable operation under a variety of conditions.

For design flexibility, the ADM7160 includes an enable pin that allows the regulator to be switched on and off, providing power-saving opportunities in battery-powered devices when the regulator is not needed. Furthermore, this LDO is stable with small ceramic output capacitors, which reduces the required board space and component cost.
