Overview
The ADPL40502AUJZ-2.8-R7 is a fixed-output low dropout linear regulator manufactured by Analog Devices Inc. It provides a stable 2.8 V output with a maximum load current of 200 mA. The device operates from an input voltage range of 2.2 V to 5.5 V and features ultra-low noise performance suitable for sensitive analog circuits. It incorporates a typical power supply rejection ratio (PSRR) of 70 dB and maintains a quiescent current of 290 uA. The regulator ensures high line regulation of 0.05 %/V and load regulation of 0.006 %/mA. It is housed in a compact TSOT-23-5 surface-mount package and supports operation across a temperature range of -40°C to +125°C.
Feature Summary
- Ultra-low noise architecture designed for precision analog applications
- Fixed 2.8 V output capability with 200 mA load drive
- High power supply rejection ratio for effective ripple suppression
- Extended industrial operating temperature range up to 125°C
Applications
- Low noise power supplies for RF front-end modules
- Precision sensor signal conditioning circuits
- Battery-powered portable instrumentation systems
- Audio equipment power regulation stages
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when sourcing components. Confirm the AUJZ designation corresponds to the TSOT-23-5 package variant required for your PCB layout. Ensure compatibility with the 2.8 V fixed output specification rather than adjustable versions within the ADPL40502 family. Cross-reference manufacturer documentation for any recent lifecycle status updates or recommended alternative part numbers.
Selection Notes
Select this component when ultra-low noise performance is critical for downstream analog signals. The 200 mA current rating suits moderate load requirements without excessive heat dissipation. Verify that the input voltage remains above the minimum dropout threshold to maintain regulation. Consider the TSOT-23-5 package size constraints during thermal management planning for enclosed designs.
Part Context
This part belongs to the ADPL40502 series of CMOS linear regulators from Analog Devices. The series focuses on delivering clean power for noise-sensitive applications while maintaining efficiency through low dropout characteristics. The AUJZ-2.8-R7 variant specifically targets designs requiring a precise 2.8 V rail in a small footprint, distinguishing it from adjustable or higher-current counterparts in the broader PMIC portfolio.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official Analog Devices resources for potential cross-references or updated revisions of the ADPL40502 series.
