Overview
The ADPL42005ARDZ-1.5-R7 is a linear voltage regulator IC from Analog Devices Inc., designed for high-voltage applications. It provides a fixed positive output of 1.5V with a maximum output current of 500mA. The device operates within an input voltage range of 4V to 20V and utilizes an 8-SOIC-EP package. As part of the ADPL42005 series, it functions as a low-dropout (LDO) regulator suitable for power management tasks requiring stable voltage regulation under varying load conditions.
Feature Summary
- Provides a fixed positive output voltage of 1.5V
- Supports up to 500mA output current capability
- Operates with input voltages ranging from 4V to 20V
- Utilizes an 8-SOIC-EP package for thermal performance
Applications
- High-voltage linear regulation in power supply circuits
- Biasing stages in analog signal processing systems
- Power management for embedded microcontroller peripherals
Procurement Notes
Verify the specific suffix R7 indicates tape-and-reel packaging when ordering. Confirm the 1.5V output variant matches system requirements, as other fixed voltages exist in the ADPL42005 family. Ensure compatibility with the 8-SOIC-EP footprint during PCB layout. Check manufacturer documentation for detailed thermal dissipation guidelines associated with this package type.
Selection Notes
Select this component when a fixed 1.5V rail is required from inputs up to 20V. Consider the 500mA current limit against peak load demands. Evaluate thermal resistance in the 8-SOIC-EP package relative to expected power dissipation. Compare against adjustable variants if flexible output settings are needed instead of the fixed 1.5V configuration.
Part Context
This part belongs to the ADPL42005 series of high-voltage LDO regulators by Analog Devices. The series includes various fixed output voltages such as 1.8V, 3.3V, and others. The ADPL42005ARDZ-1.5-R7 specifically denotes the 1.5V output version in reel packaging. It shares core architectural features with other members of the family while differing in output setpoint.
Replacement Considerations
Direct substitutes include other ADPL42005 variants with different fixed outputs like ADPL42005ARDZ-1.8-R7 or ADPL42005ARDZ-3.3-R7 if voltage levels differ. Cross-reference with similar high-voltage LDOs from other manufacturers only if pin-out and electrical characteristics match precisely.
