Overview
The ADPL42002ACPZN1.8-R7 is a low-dropout linear regulator manufactured by Analog Devices Inc., featuring a fixed 1.8V output voltage and a maximum output current of 200mA. It operates within an input voltage range of 3.8V to 20V and is housed in a compact 6-lead LFCSP package with dimensions of 2mm x 2mm. The device supports an extended operating temperature range from -40°C to +125°C, ensuring reliable performance in demanding environments.
Feature Summary
- Ultra-low noise architecture designed for sensitive analog circuits
- High power supply rejection ratio for effective ripple suppression
- Compact surface-mount packaging for space-constrained designs
Applications
- Noise-sensitive RF front-end modules
- Precision sensor signal conditioning
- Medical instrumentation power supplies
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when ordering. Confirm the 1.8V fixed output variant matches the design requirement. Check RoHS compliance status for regulatory adherence. Ensure the LFCSP-6 footprint aligns with the PCB layout. Validate thermal dissipation capabilities for the target application environment.
Selection Notes
Select this component for applications requiring ultra-low noise performance and high PSRR. The wide input voltage range accommodates various supply rails. The small form factor suits dense board layouts. Consider the fixed 1.8V output constraint during circuit design. Evaluate thermal management needs given the compact package size.
Part Context
This part belongs to the ADPL42002 series of ultra-low noise LDO regulators from Analog Devices. It shares architectural similarities with other members like the ADPL40502 but offers specific voltage and current characteristics tailored for precision applications. The series emphasizes noise reduction and stability for critical signal paths.
Replacement Considerations
Direct substitutes include other ADI ultra-low noise LDOs such as the ADP151 or ADPL40502 series, provided output voltage and current ratings match. Verify pin compatibility and thermal performance before substitution.
