Overview
The ADPL42005ARDZ-3.0-R7 is a high-voltage low-dropout linear regulator from Analog Devices Inc., housed in an 8-SOIC-EP package. It provides a fixed positive output voltage of 3.0V with a maximum load current capability of 500mA. The device operates within an input voltage range of 4V to 20V and features ultra-low noise performance, specified at 32µVrms for fixed output versions. It includes a power good indicator and user-programmable precision undervoltage lockout (UVLO). Key protection mechanisms include reverse current protection, foldback current limiting, and thermal overload protection.
Feature Summary
- Ultra-low noise output suitable for sensitive analog circuits
- High input voltage range supporting up to 20V operation
- Integrated power good status signal for system monitoring
- Comprehensive protection against reverse current and thermal stress
Applications
- Analog-to-digital converter (ADC) and digital-to-analog converter (DAC) circuit powering
- Precision amplifier biasing and supply regulation
- High-frequency oscillators and clock distribution networks
- Communication infrastructure equipment power management
- Medical and healthcare instrumentation power supplies
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when sourcing components. Confirm the 8-SOIC-EP package type matches your PCB footprint requirements. Ensure the fixed 3.0V output variant aligns with your design specifications rather than adjustable or other voltage options within the ADPL42005 family. Cross-reference manufacturer documentation for exact thermal and electrical limits.
Selection Notes
Select this component for applications requiring high input voltages up to 20V while maintaining low output noise. The 500mA current rating supports moderate load demands. Consider the SOIC-EP package for thermal dissipation needs. Evaluate the need for the power good feature and programmable UVLO against system complexity constraints compared to simpler LDO alternatives.
Part Context
This part belongs to the ADPL42005 series of high-voltage LDO regulators designed for high-performance analog and mixed-signal circuits. The series offers multiple fixed output voltages and an adjustable version, sharing common architectural benefits like high PSRR and low quiescent current. The ADPL42005ARDZ-3.0-R7 specifically denotes the 3.0V fixed output variant in tape-and-reel packaging.
Replacement Considerations
Other fixed-output variants within the ADPL42005 family, such as ADPL42005ARDZ-3.3-R7 or ADPL42005ARDZ-1.8-R7, offer different voltage levels but share identical pinouts and functional characteristics. Adjustable versions like ADPL42005ARDZ-ADJ-R7 provide flexibility but require external feedback resistors.
