Overview
The ADP7102ACPZ-5.0-R7 is a fixed-output CMOS low dropout linear regulator manufactured by Analog Devices Inc., providing a regulated 5 V output with a maximum load current of 300 mA. It operates from an input voltage range of 3.3 V to 20 V and features low noise performance, delivering 15 μV rms in the 10 Hz to 100 kHz bandwidth. The device includes reverse current protection, foldback current limiting, thermal overload protection, and a user-programmable precision undervoltage lockout function. It incorporates a power-good indicator and achieves excellent line and load transient response using only a small 1 μF ceramic output capacitor.
Feature Summary
- Provides high power supply rejection ratio and low noise for sensitive analog circuits
- Includes reverse current protection and programmable undervoltage lockout functionality
- Features a digital power-good output for system health monitoring
- Operates stably with minimal external components using small ceramic 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 component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment against the 8-lead LFCSP specification. Ensure environmental compliance documentation matches project requirements. Validate datasheet revision status prior to final design implementation.
Selection Notes
Select this regulator when a stable 5 V rail is required from higher voltage sources up to 20 V. Consider its low quiescent current for battery-operated applications. Evaluate thermal dissipation capabilities based on PCB layout and ambient temperature conditions. Verify that the 300 mA output current meets peak load demands without exceeding thermal limits.
Part Context
This component belongs to the ADP7102 series of high-voltage low dropout regulators. The series offers multiple fixed output voltage options and an adjustable variant. It utilizes advanced proprietary architecture to achieve low noise and high PSRR. The family supports various industrial and commercial applications requiring precise voltage regulation.
Replacement Considerations
Direct substitutes within the same series include ADP7102ACPZ-3.3-R7 and ADP7102ACPZ-9.0-R7 for different fixed voltages. Cross-referencing requires matching input voltage ranges, output current capabilities, and package dimensions.
