- Includes user-programmable precision undervoltage lockout and enable functions
- Features digital power-good output for system health monitoring
- Stable with small ceramic output capacitors
Applications
- Regulation for ADC and DAC circuits
- Precision amplifiers and high frequency oscillators
- Clocks and phase-locked loops
- Communications and infrastructure systems
- Medical and healthcare equipment
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 design. Ensure compatibility with the 3.3 V fixed output version. Check RoHS compliance status through official documentation before finalizing procurement.
Selection Notes
Select this component for applications requiring stable regulation from higher input voltages down to 3.3 V. Consider the low quiescent current for battery-operated devices. Evaluate thermal dissipation requirements based on the load current and input voltage differential. Ensure the PCB layout supports the exposed pad for optimal thermal performance.
Part Context
This part belongs to the ADP7102 series of high input voltage LDO regulators. The series offers multiple fixed output voltage options and an adjustable version. It is designed for high-performance analog and mixed-signal circuits operating from various rails. The family emphasizes low noise and excellent transient response.
Replacement Considerations
Check for other ADP7102 variants with different output voltages or packages if the 3.3 V fixed option is unavailable. Verify pin compatibility with alternative LDOs offering similar input ranges and current capabilities.
