Overview
The ADP7102ACPZ-3.0-R7 is a fixed-output, high-voltage CMOS low dropout linear regulator manufactured by Analog Devices Inc. It provides a regulated 3.0 V output with a maximum load current of 300 mA and operates from an input voltage range of 3.3 V to 20 V. The device features a typical quiescent current of 750 μA at full load and achieves a low dropout voltage of 200 mV under the same conditions. It incorporates reverse current protection, foldback current limiting, and thermal overload protection. The component utilizes an 8-lead LFCSP package.
Feature Summary
- Provides low noise regulation suitable for sensitive analog circuits
- Includes user-programmable precision undervoltage lockout and enable functions
- Features a digital power-good indicator for system monitoring
- Offers reverse current protection and thermal shutdown capabilities
Applications
- Regulation for ADC and DAC circuits
- Precision amplifier power supplies
- High frequency oscillator and clock circuits
- Phase-locked loop applications
- Medical and healthcare equipment
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm the exact output voltage and packaging configuration. Confirm availability status through authorized distributors as supply levels may vary. Ensure compliance with RoHS directives and check moisture sensitivity levels prior to surface mount assembly processes.
Selection Notes
Select this component when a stable 3.0 V rail is required from higher voltage sources up to 20 V. Consider the low quiescent current for battery-operated designs. Verify that the application requires the fixed 3.0 V option rather than the adjustable variant. Ensure the PCB layout supports the thermal requirements of the LFCSP package for optimal performance.
Part Context
This part belongs to the ADP7102 family of high-voltage, low-noise LDO regulators. The series offers multiple fixed output voltage options and an adjustable version. It is designed for applications requiring excellent line and load transient response with minimal external capacitance. The family supports both LFCSP and SOIC packages for flexible board design integration.
Replacement Considerations
Check for other ADP7102 variants with different output voltages or packages if the 3.0 V fixed output is not strictly required. Verify pin compatibility and thermal characteristics when substituting with similar high-voltage LDOs from other manufacturers.
