Overview
The ADP7102ARDZ-3.0-R7 is a CMOS low dropout linear regulator manufactured by Analog Devices Inc. It operates from an input voltage range of 3.3 V to 20 V and provides up to 300 mA of output current. This specific variant features a fixed 3.0 V output with an initial accuracy of ±0.8%. The device delivers low noise performance, specified at 15 μV rms for fixed output versions, and achieves a power supply rejection ratio of 60 dB at 10 kHz. It includes reverse current protection, foldback current limit, thermal overload protection, and a user-programmable precision UVLO/enable function alongside a power-good indicator.
Feature Summary
- Provides low noise regulation suitable for sensitive analog circuits
- Includes reverse current protection and thermal overload safeguards
- Features a programmable undervoltage lockout and power-good status indicator
Applications
- ADC and DAC circuit regulation
- Precision amplifier power supplies
- High frequency oscillator and clock stabilization
- Phase-locked loop applications
- Medical and healthcare equipment power management
Procurement Notes
Verify the exact ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure compatibility with required PCB layout guidelines regarding minimum capacitance and exposed pad grounding. Confirm availability status through authorized distributors as supply conditions may vary.
Selection Notes
Select this component when a stable 3.0 V rail is required from higher voltage sources up to 20 V. Consider its low quiescent current for battery-operated portable equipment. Verify that the application load does not exceed the 300 mA maximum rating and that the input-to-output differential remains within dropout specifications.
Part Context
This part belongs to the ADP7102 family of high input voltage LDOs designed for high-performance analog and mixed-signal circuits. The series offers multiple fixed output options and an adjustable version, all sharing common architectural benefits such as stability with small ceramic capacitors and robust protection features.
Replacement Considerations
Consult the official datasheet ordering guide for direct pin-compatible alternatives within the same family. Verify electrical parameters and package dimensions before substituting.
