Overview
The ADP7118ARDZ-5.0-R7 is a CMOS low dropout linear regulator manufactured by Analog Devices Inc., providing a fixed 5.0 V output with a maximum current of 200 mA. It operates from an input voltage range of 2.7 V to 20 V and features ultralow noise of 11 µV rms. The device includes precision enable, user-programmable soft start, and thermal shutdown protection. It is housed in a compact 6-lead LFCSP package (2 mm × 2 mm) and is qualified for automotive applications under AEC-Q100 standards.
Feature Summary
- Ultralow output noise of 11 µV rms independent of the fixed output voltage setting
- High power supply rejection ratio reaching 88 dB at 10 kHz
- User-programmable soft start capability via external capacitor in LFCSP and SOIC packages
- Precision enable pin with programmable logic thresholds and hysteresis
Applications
- Regulation for noise-sensitive analog and mixed-signal circuits
- Powering ADC and DAC circuits alongside precision amplifiers
- Providing power for VCO VTUNE control in communications systems
- Medical and healthcare equipment requiring stable voltage rails
- Industrial instrumentation and infrastructure applications
Procurement Notes
Verify that the specific suffix RDZ corresponds to the 8-Lead SOIC package variant rather than the standard LFCSP configuration. Confirm the R7 designation indicates reel packaging. Ensure the component meets AEC-Q100 automotive qualification requirements if intended for vehicle electronics. Cross-reference the datasheet revision H specifications against the manufacturing lot date code to ensure compliance with the latest design parameters.
Selection Notes
Select this component when designing systems requiring high input voltages up to 20 V with minimal output noise. The adjustable architecture allows increasing the fixed 5.0 V output using an external divider while maintaining stability. Consider the thermal resistance characteristics of the SOIC package for high-current loads. Utilize the ADIsimPower tool to optimize the bill of materials and verify transient response performance under varying load conditions.
Part Context
This part belongs to the ADP7118 family of low-noise CMOS LDO regulators designed for high-performance analog applications. The series supports various fixed output voltages ranging from 1.2 V to 5.0 V and offers adjustable configurations. The family is characterized by low quiescent current and excellent line/load regulation, making it suitable for portable and battery-powered devices requiring precise voltage regulation.
Replacement Considerations
Direct substitutes within the same family include ADP7118ACPZN3.3-R7 and ADP7118WAUJZ-5.0-R7, which share identical electrical specifications but differ in package type or output voltage.
