Overview
The ADPL40502AUJZ-1.5-R7 is a low-dropout linear regulator manufactured by Analog Devices Inc., designed for ultra-low noise applications. It provides a fixed output voltage of 1.5 V with a maximum load current capability of 200 mA. The device operates within an input voltage range from 2.2 V to 5.5 V and features a typical power supply rejection ratio (PSRR) of 70 dB. It incorporates comprehensive protection mechanisms including overcurrent, thermal overload, and under-voltage lockout. The component is housed in a compact LFCSP-6 surface-mount package and supports operation across an extended temperature range from -40 °C to +125 °C.
Feature Summary
- Ultra-low noise architecture optimized for sensitive analog and mixed-signal circuits
- Integrated protection functions including overcurrent limiting, thermal shutdown, and under-voltage lockout
Applications
- Powering high-performance analog circuits requiring clean voltage rails
- Supplying mixed-signal integrated circuits to minimize noise interference
- Portable electronic devices where low dropout and stable regulation are critical
Procurement Notes
Verify the specific suffix AUJZ against official manufacturer documentation to confirm pinout compatibility and package dimensions. Confirm that the 1.5 V fixed output variant matches the system design requirements. Check for any recent product change notices or lifecycle status updates directly from Analog Devices before finalizing procurement plans.
Selection Notes
Select this component when circuit designs demand minimal output noise alongside moderate current delivery capabilities. Ensure the available input voltage remains above the minimum threshold while accounting for dropout voltage at peak load conditions. Evaluate the thermal performance within the LFCSP-6 package to ensure reliable operation across the specified industrial temperature range.
Part Context
This part belongs to the ADPL40502 series of ultra-low noise LDO regulators from Analog Devices. The series is engineered to support demanding applications such as RF front-ends and precision data converters. The AUJZ suffix indicates the specific TSOT-23-5 or similar small outline package configuration used for space-constrained PCB layouts.
Replacement Considerations
Consult official Analog Devices cross-reference guides for verified substitutes. Verify that alternative components match the 1.5 V output, 200 mA current rating, and low-noise specifications.
