ADPL40502ACPZ-1.8-R7

Overview

The ADPL40502ACPZ-1.8-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 1.8 V with a maximum output current capability of 200 mA. The device operates within an input voltage range of 2.2 V to 5.5 V and features a typical power supply rejection ratio (PSRR) of 70 dB. Quiescent current consumption is specified at 290 uA. The unit supports operation across a temperature range from -40°C to +125°C and is housed in an LFCSP-6 surface-mount package.

Feature Summary

Ultra-low noise architecture optimized for sensitive analog circuits
Fixed 1.8 V output configuration for stable power delivery
High power supply rejection ratio to minimize ripple and noise

Applications

Powering noise-sensitive RF front-end modules
Supplying precision sensor interfaces requiring clean DC rails
Biasing high-performance data converters

Procurement Notes

Verify the specific suffix R7 against official Analog Devices documentation to confirm reel packaging specifications. Ensure the part number matches the exact 1.8 V output variant, as other voltage options exist within the same series. Cross-reference the LFCSP-6 footprint dimensions with your PCB layout guidelines before finalizing procurement decisions.

Selection Notes

Select this component when circuit requirements demand minimal output noise and high PSRR rather than ultra-low quiescent current. The 200 mA output limit suits moderate load applications. Consider thermal dissipation capabilities given the small LFCSP-6 package size under continuous load conditions.

Part Context

This device belongs to the ADPL40502 series of low-dropout regulators. It shares architectural similarities with other Analog Devices ultra-low noise LDOs but is distinct from higher-current or adjustable variants. The series targets applications where signal integrity is critical over raw efficiency metrics.
