Overview
The ADPL40502AUJZ-3.3-R7 is a low-dropout linear regulator manufactured by Analog Devices Inc., featuring a fixed 3.3 V output and a maximum output current of 200 mA. It operates within an input voltage range of 2.2 V to 5.5 V and utilizes an LFCSP-6 surface-mount package. The device maintains a typical quiescent current of 290 uA and delivers a typical power supply rejection ratio of 70 dB. It supports operation across a temperature range from -40 C to +125 C, with a maximum dropout voltage of 230 mV at full load.
Feature Summary
- Ultra-low noise architecture designed for sensitive analog circuitry
- Integrated enable control for efficient power management
- Comprehensive protection against overcurrent and thermal overload
Applications
- Portable battery-powered instrumentation
- Wireless communication modules
- Medical monitoring devices
Procurement Notes
Verify the specific suffix AUJZ corresponds to the LFCSP-6 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering code matches the exact electrical specifications required for the target application design.
Selection Notes
Select this component for applications requiring ultra-low noise performance in a compact footprint. Compare the 200 mA output capability against system peak loads. Evaluate the 290 uA quiescent current impact on overall battery life relative to alternative regulators in the same series.
Part Context
This part belongs to the ADPL50402 series of ultra-low noise LDOs. It shares architectural similarities with other members but differs in package type and specific electrical characteristics. The series targets high-performance portable electronics where noise sensitivity is critical.
Replacement Considerations
Check the ADPL40502ACPZ-3.3-R7 for pin-compatible alternatives in different packages. Verify that substitute parts maintain equivalent noise performance and dropout voltage requirements.
