Overview
The ADPL40502ACPZ-3.0-R7 is a low-dropout linear regulator manufactured by Analog Devices Inc., featuring an ultra-low noise architecture and a fixed 3 V output voltage. It supports a maximum output current of 200 mA with a typical dropout voltage of 150 mV at full load, reaching a maximum of 230 mV. The device operates within an input voltage range of 2.2 V to 5.5 V and maintains a quiescent current of 290 uA. It provides high power supply rejection ratio (PSRR) performance with a typical value of 70 dB. Line regulation is specified at 0.05 %/V, while load regulation is 0.006 %/mA. The component is housed in an LFCSP-6 package and functions reliably across an operating temperature range from -40 C to +125 C.
Feature Summary
- Ultra-low noise design optimized for sensitive analog circuits
- Fixed 3 V output capability with 200 mA drive strength
- High power supply rejection ratio for stable operation under varying line conditions
Applications
- Noise-sensitive sensor signal conditioning
- Portable battery-powered instrumentation
- RF front-end power supply filtering
Procurement Notes
Verify the specific suffix R7 indicates reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the LFCSP-6 thermal pad soldering process aligns with industry standards for surface-mount devices. Validate that the 3.0 V output matches the target circuit requirements exactly, as this variant is not adjustable.
Selection Notes
Select this component when ultra-low noise performance is critical alongside moderate current delivery. The 290 uA quiescent current offers a balance between efficiency and noise suppression compared to standard LDOs. The wide input voltage range up to 5.5 V allows flexibility in system power architectures. Consider the LFCSP-6 package size constraints during PCB layout planning to ensure adequate thermal dissipation and mechanical stability.
Part Context
This part belongs to the ADPL50402 series of low-dropout regulators from Analog Devices. It is designed specifically for applications requiring clean power supplies without the complexity of switching regulators. The fixed 3.0 V output distinguishes it from adjustable variants within the same family, providing a straightforward solution for standard logic or analog rail generation.
Replacement Considerations
Check for direct pin-compatible alternatives within the ADPL50402 series if different output voltages are required. Verify that any substitute maintains the 200 mA output current capability and similar noise specifications. Ensure the replacement package remains LFCSP-6 to fit existing footprints.
