ADM7170ACPZ-3.0-R7

Overview

The ADM7170ACPZ-3.0-R7 is a fixed-output, positive linear regulator from Analog Devices Inc., housed in an 8-lead LFCSP-WD (3x3) package. It delivers up to 500 mA of load current with a fixed output voltage of 3.0 V. The device operates within an input voltage range of 2.3 V to 6.5 V and features ultralow noise performance of 5 µV rms across the 100 Hz to 100 kHz bandwidth. It achieves a power supply rejection ratio of 60 dB at 100 kHz and maintains a low dropout voltage of 42 mV at full load.

Feature Summary

Ultralow noise architecture providing stable regulation for sensitive analog circuits
High power supply rejection ratio ensuring effective filtering of input supply ripple
Fast transient response capability to handle rapid load step changes efficiently
Precision enable pin with defined logic thresholds for reliable system control

Applications

Noise-sensitive ADC and DAC circuit regulation
Precision amplifier power supplies
PLL/VCO and clocking IC power rails
Medical and healthcare instrumentation systems
Industrial and infrastructure communications equipment

Procurement Notes

Verify the specific suffix R7 indicates tape and reel packaging when sourcing components. Confirm that the fixed 3.0 V output variant matches the design requirement, as other voltage options exist within the ADM7170 family. Ensure compatibility with the required 8-lead LFCSP footprint during PCB layout planning.

Selection Notes

Select this component for applications requiring high current delivery with minimal output noise. Verify that the input voltage remains above the minimum threshold while accounting for dropout characteristics under maximum load conditions. Consider thermal dissipation requirements based on the junction-to-ambient resistance of the selected package type.

Part Context

This part belongs to the ADM7170 series of CMOS low dropout linear regulators designed for high-performance mixed-signal applications. The series offers various fixed output voltages and adjustable versions to accommodate different rail requirements. It shares architectural similarities with higher-current variants like the ADM7171 and ADM7172.
