ADM7170ACPZ-5.0-R7

Overview

The ADM7170ACPZ-5.0-R7 is a fixed-output, positive linear regulator from Analog Devices Inc., housed in an 8-lead LFCSP package. It delivers up to 500 mA of load current with a nominal output voltage of 5.0 V. The device operates within an input voltage range of 2.3 V to 6.5 V and maintains a low dropout voltage of 42 mV at full load. Key electrical specifications include a quiescent current of 0.7 mA, shutdown current of 0.25 μA, and initial accuracy of ±0.75%. It features high power supply rejection ratio (PSRR) of 60 dB at 100 kHz and ultralow output noise of 5 μV rms.

Feature Summary

Ultralow noise performance independent of output voltage
Fast transient response for rapid load step changes
High power supply rejection ratio across frequency ranges
Precision enable pin with adjustable soft start capability

Applications

Regulation for ADC and DAC circuits
Powering precision amplifiers
Supplying PLLs, VCOs, and clocking ICs
Communications and infrastructure systems
Medical and healthcare equipment

Procurement Notes

Verify the specific ordering suffix matches the required packaging format before procurement. Confirm that the fixed 5.0 V output variant aligns with system design requirements, as adjustable versions utilize external feedback dividers. Ensure component authenticity through authorized distribution channels to maintain reliability standards.

Selection Notes

Select this component when low noise and fast transient response are critical for sensitive analog loads. The fixed 5.0 V output eliminates the need for external resistors compared to adjustable variants. Consider thermal dissipation requirements based on the input-to-output voltage differential and maximum load current in the final application layout.

Part Context

This part belongs to the ADM7170 family of CMOS low dropout linear regulators designed for high-performance mixed-signal applications. It shares architectural similarities with the ADM7171 and ADM7172 series but offers a lower 500 mA current rating. The device utilizes proprietary technology to achieve excellent line and load regulation using small ceramic capacitors.
