Overview
The ADPL42005ACPZ-1.8-R7 is a single-channel, positive fixed-output Low Dropout (LDO) linear regulator manufactured by Analog Devices Inc. It provides a fixed output voltage of 1.8V with a maximum output current capability of 500mA. The device operates within an input voltage range of 4V to 20V and features low noise performance with an output noise voltage of 32µVrms. It includes integrated protection mechanisms such as reverse current protection, foldback current limiting, and thermal overload protection.
Feature Summary
- Provides stable power for high-performance analog and mixed-signal circuits
- Features low noise characteristics suitable for sensitive applications
- Includes comprehensive protection against overcurrent and thermal stress
Applications
- Analog-to-digital converter (ADC) and digital-to-analog converter (DAC) circuits
- Precision amplifier stages
- High-frequency oscillators and clock distribution networks
- Communication and infrastructure systems
- Medical and healthcare equipment
Procurement Notes
Verify the specific package type and tape-and-reel configuration when ordering. Confirm that the fixed 1.8V output aligns with system requirements. Ensure compatibility with the required input voltage range of 4V to 20V. Check for any specific handling instructions related to electrostatic discharge during assembly.
Selection Notes
Select this component for designs requiring low-noise regulation in mixed-signal environments. Consider the 500mA current limit and 4V minimum input voltage. Evaluate the need for reverse current protection and programmable UVLO if present in the design. Compare dropout voltage specifications against available headroom.
Part Context
This part belongs to the ADPL42005 series of LDO regulators designed for demanding analog applications. The series offers various fixed output voltages and a adjustable version. It utilizes a proprietary architecture to achieve high power supply rejection ratio and excellent transient response across line, load, and temperature variations.
Replacement Considerations
Direct substitutes include other parts from the ADPL42005 family with different fixed output voltages or the adjustable variant. Verify pinout compatibility and electrical specifications before substitution.
