Overview
The ADP7118ARDZ-2.5-R7 is a CMOS low dropout linear regulator manufactured by Analog Devices Inc. It operates from an input voltage range of 2.7 V to 20 V and provides up to 200 mA of output current. The device features a fixed output voltage of 2.5 V with an initial accuracy of ±0.8%. It delivers ultralow output noise of 11 µV rms and high power supply rejection ratios, reaching 88 dB at 10 kHz. The quiescent current is typically 50 µA with no load, dropping to 3 µA in shutdown mode. It includes precision enable functionality and user-programmable soft start capabilities.
Feature Summary
- Ultralow output noise performance independent of the fixed output voltage setting
- High power supply rejection ratio across a wide frequency spectrum
- Precision enable pin with programmable logic thresholds and hysteresis
- User-programmable soft start using an external capacitor
Applications
- Regulation for noise-sensitive analog circuits
- Powering ADC and DAC circuits
- Supplying precision amplifiers
- Powering VCO VTUNE control lines
- Medical and healthcare instrumentation systems
Procurement Notes
Verify the specific package type and tape-and-reel configuration against the datasheet ordering guide. Confirm that the component meets AEC-Q100 automotive qualification requirements if intended for such environments. Ensure the selected variant matches the required fixed output voltage and thermal specifications for the target application.
Selection Notes
Select this regulator when a stable 2.5 V rail is required from higher voltage sources up to 20 V. Consider the 2.2 µF minimum ceramic output capacitance requirement for stability. Evaluate the thermal resistance characteristics relative to the expected load current and ambient temperature conditions to ensure junction temperatures remain within safe operating limits.
Part Context
This component belongs to the ADP7118 family of low noise LDO regulators. The series offers multiple fixed output voltage options ranging from 1.2 V to 5.0 V. It is designed for high-performance mixed-signal applications requiring excellent line and load transient response. The architecture supports adjustable output voltages above the fixed set point using external feedback dividers.
Replacement Considerations
Consult the official Analog Devices ADP7118 datasheet ordering guide for confirmed substitute part numbers. Verify compatibility regarding output voltage, package dimensions, and electrical specifications before implementation.
