Procurement Notes
Verify the specific suffix R7 indicates tape and reel packaging when sourcing. Confirm the ACPZ designation corresponds to the LFCSP package variant required for your design. Ensure compatibility with the 3.3 V to 20 V input range and 500 mA load requirements. Check for RoHS compliance status if mandated by your manufacturing standards.
Selection Notes
Select this component for applications requiring high input voltage tolerance up to 20 V. It is suitable for designs needing low quiescent current operation. Consider the LFCSP package for compact footprint requirements. Verify that the output capacitor selection meets the minimum capacitance and ESR specifications for stability.
Part Context
This part belongs to the ADP7104 family of low dropout regulators. The series supports various fixed output voltages and adjustable configurations. It is designed for high-performance analog and mixed-signal circuits. The family emphasizes low noise and excellent transient response capabilities.
Replacement Considerations
Check for ADP7104 variants with different output voltages or packages. Verify pin compatibility if substituting with other LDOs. Ensure equivalent thermal performance and current handling capabilities are maintained.
