ADPL42005ACPZ-3.3-R7

Overview

The ADPL42005ACPZ-3.3-R7 is a low-dropout linear regulator (LDO) from Analog Devices Inc., designed for high-performance analog and mixed-signal circuits. It operates within an input voltage range of 4V to 20V and provides a fixed output voltage of 3.3V with a maximum output current of 500mA. The device features a low noise profile of 32µVrms, ensuring clean power delivery for sensitive applications. It includes a power good indicator and user-programmable precision undervoltage lockout. The component is housed in an 8-lead LFCSP package and supports operation across a temperature range of -40°C to +125°C.

Feature Summary

Provides stable 3.3V output with up to 500mA load capability for noise-sensitive circuits
Features ultra-low output noise of 32µVrms independent of output voltage setting
Includes digital power good status output for system monitoring and sequencing
Offers programmable precision undervoltage lockout for multi-supply control

Applications

Analog-to-digital converter (ADC) and digital-to-analog converter (DAC) power supplies
High-frequency oscillators and clock distribution networks
Precision amplifier biasing in instrumentation systems
Phase-locked loop (PLL) circuit regulation

Procurement Notes

Verify the specific suffix 'R7' indicates reel packaging when sourcing. Confirm the 'ACPZ' designation corresponds to the LFCSP package variant required for your layout. Ensure the fixed 3.3V output matches your design requirements, as other voltage options exist within the ADPL42005 family. Cross-reference the manufacturer part number with official distributor catalogs to confirm availability and authenticity.

Selection Notes

Select this component when designing for high-linearity applications requiring minimal noise injection. The 500mA current rating suits moderate-power analog sections. Consider the 4V minimum input voltage constraint against your supply rails. The integrated power good signal simplifies reset logic design. Evaluate thermal performance based on the expected voltage drop and load current in the target application environment.

Part Context

This part belongs to the ADPL42005 series of CMOS LDO regulators. The series is engineered for superior power supply rejection ratio (PSRR) and transient response. It complements other Analog Devices power management solutions by offering precise voltage regulation for critical signal chains. The family includes both fixed and adjustable output variants to accommodate diverse system architectures.
