ADM7171ACPZ-3.3-R7 Description

Short technical summary and product information.

The ADM7171ACPZ-3.3-R7 is a high-performance CMOS low dropout linear regulator (LDO) from Analog Devices, designed to provide up to 1A of output current. Operating from an input voltage range of 2.3V to 6.5V, this regulator delivers a stable fixed 3.3V output.

 

Key features include ultralow noise (5 μV rms) and high Power Supply Rejection Ratio (PSRR) of 60 dB at 100 kHz, making it suitable for noise-sensitive applications like ADC/DAC circuits and precision amplifiers. It offers fast transient response (1.5 μs for a 1 mA to 500 mA load step) and a low dropout voltage of 42 mV at 500 mA load. The device also features precision enable and adjustable soft start control.

 

Packaged in an 8-lead LFCSP-WD (3x3mm) with surface mount capability, the ADM7171ACPZ-3.3-R7 is designed for compact and efficient power management solutions in communications, medical, and industrial systems.
