Overview
The ADM7151ACPZ-02-R2 is an ultralow noise, high PSRR RF linear regulator from Analog Devices. It delivers up to 800 mA of output current with an input voltage range of 4.5 V to 16 V. The adjustable output voltage spans 1.5 V to 5.1 V. Key electrical parameters include a quiescent current of 4.3 mA at no load and a shutdown current of 0.1 µA. Noise performance is characterized by 1.0 µV rms integrated noise (100 Hz to 100 kHz) and a spectral density of 1.7 nV/√Hz (10 kHz to 1 MHz). Power supply rejection ratio exceeds 90 dB from 1 kHz to 100 kHz at a 400 mA load. The device operates within a temperature range of -40°C to +125°C.
Feature Summary
- Ultralow noise architecture providing exceptional signal integrity for sensitive RF circuits
- High power supply rejection ratio maintained across wide frequency ranges
- Optimized for stability with standard ceramic output capacitors
- Integrated thermal overload and current-limit protection
Applications
- RF mixers and phase-locked loops
- Voltage-controlled oscillators
- Clock distribution circuits
- Ultrasound imaging applications
- High-speed analog-to-digital converters
Procurement Notes
Verify the specific suffix R2 against official documentation to confirm reel packaging specifications. Confirm that the ACPZ designation corresponds to the LFCSP package type required for your design. Ensure compatibility with the -02 model variant regarding input-output voltage headroom requirements. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and revision status before procurement.
Selection Notes
Select this component when designing systems requiring low noise and high PSRR for RF signals. The -02 model variant is optimized for specific input-output voltage combinations to minimize power dissipation. Ensure the application utilizes ceramic capacitors as specified for stability. Evaluate thermal performance based on the expected load current and ambient operating conditions to maintain junction temperatures within safe limits.
Part Context
This component belongs to the ADM7151 family of linear regulators designed for radio frequency applications. It features a P-channel MOSFET pass transistor controlled by an error amplifier. The device includes an internal active ripple filter to isolate the low-noise LDO from input voltage noise. It is available in compact surface-mount packages suitable for space-constrained designs.
Replacement Considerations
Direct substitutes are not explicitly listed in the provided documentation. Consider other models within the ADM7151 series or the ADP715x family if pinout and electrical characteristics align. Verify that any replacement maintains the required ultralow noise and high PSRR specifications for the specific RF application.
