ADM7170ACPZ-R7

Overview

The ADM7170ACPZ-R7 is a CMOS low dropout linear regulator (LDO) from Analog Devices Inc. It operates with an input voltage range of 2.3 V to 6.5 V and provides up to 500 mA of output current. The device features ultralow noise, high power supply rejection ratio (PSRR), and fast transient response. It is available in adjustable output configurations ranging from 1.2 V to VIN minus dropout voltage. The component utilizes a proprietary architecture to achieve excellent line and load transient performance using only a small 4.7 µF ceramic output capacitor.

Feature Summary

Ultralow noise performance independent of output voltage
High power supply rejection ratio for sensitive analog circuits
Fast transient response capability with minimal output capacitance
Adjustable output voltage via external feedback divider

Applications

ADC and DAC circuit regulation
Precision amplifier power supplies
PLL/VCO and clocking ICs
Medical and healthcare equipment
Industrial instrumentation systems

Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest ordering guide to ensure authenticity. Confirm that the R7 suffix corresponds to the correct reel packaging format required for your assembly process. Cross-reference the datasheet revision to ensure all electrical specifications match your design requirements before finalizing procurement.

Selection Notes

Select this component when designing noise-sensitive analog or mixed-signal circuits requiring high current delivery. Ensure the application maintains an input-to-output differential greater than the specified dropout voltage across the full operating temperature range. Verify that the chosen output capacitors meet the minimum capacitance and ESR requirements for stability.

Part Context

This LDO belongs to the ADM7170 series, designed for high-performance applications where power integrity is critical. It serves as a compact solution for stepping down voltages in portable and battery-operated devices. The device integrates thermal overload and current-limit protection to safeguard connected loads during fault conditions.
