Overview
The ADPL42005ACPZ-5.0-R7 is a low-dropout linear regulator manufactured by Analog Devices Inc., designed for high-performance analog and mixed-signal circuits. It provides a fixed 5.0V output with a maximum load current of 500mA. The device operates within an input voltage range of 4V to 20V. Key electrical specifications include an output noise voltage of 32µVrms, a power supply rejection ratio (PSRR) of 58dB at 10kHz, and an initial accuracy of ±0.8%. The typical dropout voltage is 400mV at full load, with a quiescent current of 900µA under standard conditions.
Feature Summary
- Features advanced proprietary architecture delivering high power supply rejection and low noise performance suitable for sensitive applications.
- Includes comprehensive protection mechanisms such as reverse current protection, foldback current limiting, and thermal overload protection.
- Offers user-programmable precision undervoltage lockout and enable functionality for flexible power sequencing control.
Applications
- High-frequency oscillators and clock circuits
- Communication and infrastructure systems
- Medical and healthcare equipment
- Industrial instrumentation
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when sourcing components. Confirm the ACPZ designation corresponds to the LFCSP package type required for your layout. Ensure compatibility with the 4V to 20V input range for your system design. Cross-reference the 5.0V fixed output version against schematic requirements. Validate that the 500mA current rating meets peak load demands.
Selection Notes
Select this component for designs requiring low noise and high PSRR in mixed-signal environments. Consider the 500mA output capability for moderate load applications. Evaluate the 4V to 20V input range against available supply rails. Assess the need for programmable UVLO features for complex power management sequences. Compare the 32µVrms noise specification against other regulators in the portfolio.
Part Context
This part belongs to the ADPL42005 series of low-dropout regulators from Analog Devices. The series includes multiple fixed output voltages and a adjustable version. It shares architectural similarities with other high-performance LDOs but is distinct in its specific input range and noise characteristics. The family targets industrial and medical markets requiring stable power delivery.
Replacement Considerations
Direct substitutes may include other ADPL42005 variants with different output voltages if voltage adjustment is possible via external resistors, though fixed versions are not interchangeable. Verify pinout compatibility before considering alternative packages or manufacturers. Check datasheet specifications for equivalent PSRR and noise levels.
