Overview
The ADPL44002AUJZ-R7 is a low-dropout linear regulator manufactured by Analog Devices Inc. It provides an adjustable output voltage with a maximum input voltage of 40V and a continuous output current capability of 200mA. The device operates within an extended temperature range from -40°C to +125°C and features a typical power supply rejection ratio of 78dB. Key electrical parameters include a quiescent current of 80µA, a minimum dropout voltage of 220mV, and a maximum of 450mV at full load. Line regulation is specified at 0.01%/V, while load regulation is 0.002%/mA. The component utilizes an LFCSP-6 surface-mount package.
Feature Summary
- Supports high input voltages up to 40V for flexible power supply architectures
- Provides adjustable output voltage for customized system requirements
- Ensures stable operation across wide industrial temperature ranges
Applications
- Industrial control systems requiring robust voltage regulation
- Automotive electronics operating under varying load conditions
- Communication equipment needing low-noise power delivery
Procurement Notes
Verify the specific suffix and tape-and-reel packaging configuration against official Analog Devices documentation before procurement. Confirm that the LFCSP-6 footprint matches your PCB design constraints. Ensure compliance with RoHS directives and check for any regional distribution restrictions or limited availability status directly from authorized suppliers.
Selection Notes
Select this component when a high-voltage input tolerance combined with an adjustable output is required in a compact form factor. The low quiescent current makes it suitable for battery-powered applications where efficiency is critical. Verify that the thermal performance of the LFCSP-6 package meets the dissipation requirements of your specific application environment.
Part Context
This part belongs to the ADPL44002 series of low-dropout regulators designed for high-voltage applications. It shares core architectural features with other members of the family but differs in output configuration and packaging. The AUJZ suffix indicates a specific pin-compatible variant within the broader product line, ensuring interchangeability with related components in existing designs.
Replacement Considerations
Direct substitutes may include other ADPL44002 variants with fixed outputs or different packages, provided they meet the 40V input and 200mA output specifications. Cross-reference pinouts and thermal characteristics carefully to ensure compatibility without redesigning the printed circuit board.
