ADM7160AUJZ-2.5-R7

The ADM7160AUJZ-2.5-R7 is an ultralow noise, low dropout linear regulator from Analog Devices, capable of delivering up to 200mA of output current. It operates with an input voltage range of 2.2V to 5.5V and provides a fixed 2.5V output. This regulator is designed for noise-sensitive analog front-end and RF applications, achieving ultralow noise performance without the need for a bypass capacitor.

Key electrical characteristics include a low dropout voltage of 150mV at a 200mA load, ensuring improved efficiency. The device offers excellent PSRR performance of 54dB at 100kHz and ultralow noise levels, such as 3 µV rms from 0.1 Hz to 10 Hz. Accuracy over line, load, and temperature is within −2.5%/+1.5% with an initial accuracy of ±1%.

Protection features include current-limit and thermal overload protection, preventing damage under adverse conditions. The ADM7160AUJZ-2.5-R7 is designed for stable operation with small 1 µF ceramic input and output capacitors, making it suitable for high-performance, space-constrained applications. It is housed in a compact 5-lead TSOT package, ideal for surface mounting.

This linear regulator is well-suited for applications such as ADC/DAC power supplies, RF, VCO, and PLL power supplies, and post dc-to-dc regulation where low noise and high performance are critical.
