Overview
The ADP7118ACPZN2.5-R7 is a 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 regulator includes user-programmable soft start functionality and precision enable control. It is housed in a compact 6-lead LFCSP package.
Feature Summary
- Ultralow output noise performance independent of the fixed output voltage setting
- High power supply rejection ratio across various frequencies for sensitive analog circuits
- User-programmable soft start capability via external capacitor in LFCSP packages
- Precision enable pin with adjustable logic thresholds and hysteresis
Applications
- Regulation for noise-sensitive applications
- Powering ADC and DAC circuits
- Supplying precision amplifiers
- Providing power for VCO VTUNE control
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and reel specifications. Ensure compatibility with the required output voltage option and check for automotive qualification status if applicable to the target environment. Confirm availability through authorized distribution channels as stock levels may vary.
Selection Notes
Select this component when designing systems requiring a wide input voltage range down to low output rails. Consider the thermal resistance characteristics of the LFCSP package for high-current applications. Evaluate the need for external soft-start capacitors based on inrush current requirements. Verify that the minimum output capacitance requirements are met using appropriate ceramic dielectrics.
Part Context
This part belongs to the ADP7118 series of CMOS LDO linear regulators designed for high-performance analog and mixed-signal circuits. The series offers multiple fixed output voltage options and adjustable configurations. It is supported by design tools like ADIsimPower for schematic generation and performance optimization.
Replacement Considerations
Consult the manufacturer's datasheet for officially listed alternative part numbers within the same family or cross-reference compatible devices. Ensure any substitute matches the electrical specifications, package dimensions, and thermal performance requirements.
