The Analog Devices ADM7172ACPZ-R7 is a high-performance, ultralow noise, high Power Supply Rejection Ratio (PSRR) CMOS linear voltage regulator (LDO). It operates from an input voltage range of 2.3 V to 6.5 V and can deliver up to 2 A of output current. This LDO is designed for noise-sensitive applications such as ADC and DAC circuits, precision amplifiers, and clocking ICs.
Key electrical characteristics include a low noise level of 5 µV rms (independent of output voltage at 100 Hz to 100 kHz), a fast transient response of 1.5 μs for a 1 mA to 1.5 A load step, and a PSRR of 60 dB at 100 kHz. The dropout voltage is typically 172 mV at a 2 A load when the output is 3 V. The device offers adjustable output voltage options from 1.2 V to VIN − VDO, with fixed output voltage options also available.
The ADM7172ACPZ-R7 is available in an 8-lead 3 mm × 3 mm LFCSP package, suitable for surface mounting. It features precision enable and adjustable soft start control features. Protection includes over current and over temperature.
This LDO is well-suited for applications requiring clean power rails, such as communications infrastructure, medical and healthcare devices, and industrial instrumentation.
