ADM7172ACPZ-2.5-R7 Description

Short technical summary and product information.

The ADM7172ACPZ-2.5-R7 is a high-performance CMOS LDO voltage regulator from Analog Devices, designed to provide up to 2A of output current. Operating from an input voltage range of 2.3V to 6.5V, it is suitable for regulating power for noise-sensitive applications such as ADC/DAC circuits, precision amplifiers, and clocking ICs.

 

Key electrical characteristics include ultralow noise of 5 µV rms, a high PSRR of 60 dB at 100 kHz, and fast transient response of 1.5 μs. The device features a low dropout voltage of 172 mV at a 2A load when VOUT is 3V. It offers an initial accuracy of -0.5% to +1% and an operating accuracy of ±1.5% over line, load, and temperature variations.

 

The ADM7172ACPZ-2.5-R7 is available in an 8-lead 3mm x 3mm LFCSP package, suitable for surface mounting. It supports adjustable and fixed output voltages ranging from 1.2V to 5.0V, with this specific part number featuring a fixed 2.5V output. The regulator also includes features like precision enable and adjustable soft start for controlled power-up sequences.
