ADPL40502AUJZ-1.2-R7

Overview

The ADPL40502AUJZ-1.2-R7 is a low-dropout linear regulator manufactured by Analog Devices Inc., featuring a fixed 1.2 V output and a maximum continuous output current of 200 mA. It operates within an input voltage range of 2.2 V to 5.5 V and maintains a typical dropout voltage of 150 mV at full load. The device incorporates ultra-low noise architecture with a power supply rejection ratio (PSRR) of 70 dB, ensuring clean power delivery for sensitive analog circuits. Quiescent current is specified at 290 uA, supporting efficient operation in battery-powered applications. It is housed in a compact LFCSP-6 surface-mount package and supports an extended industrial operating temperature range from -40°C to +125°C.

Feature Summary

Ultra-low noise design optimized for precision analog signal integrity
High power supply rejection ratio for effective ripple suppression
Compact LFCSP-6 footprint suitable for space-constrained layouts

Applications

Precision sensor biasing requiring minimal voltage noise
RF front-end power conditioning
Portable medical instrumentation

Procurement Notes

Verify the specific suffix AUJZ against official Analog Devices documentation to confirm the TSOT-23-5 package variant differs from the ACPZ version. Confirm RoHS compliance status directly via the manufacturer datasheet before integration. Ensure ESD handling protocols are followed during assembly due to the small form factor.

Selection Notes

Select this component when ultra-low noise performance is critical for downstream analog stages. Compare quiescent current specifications against system power budgets. Verify that the 200 mA output capability meets peak load requirements without exceeding thermal limits in the chosen enclosure environment.

Part Context

This part belongs to the ADPL40502 series of low-noise LDO regulators designed for high-performance applications. The series emphasizes noise reduction techniques typically found in higher-cost discrete solutions, integrated into a single monolithic IC. It complements other Analog Devices PMIC offerings by providing dedicated clean power rails for ADCs and oscillators.
