Overview
The ADP7159ACPZ-02-R7 is an adjustable linear regulator from Analog Devices, operating within a 2.3 V to 5.5 V input voltage range and delivering up to 2 A of load current. It features ultralow noise performance with 0.9 µV rms integrated noise (100 Hz to 100 kHz) and high power supply rejection ratio (PSRR). The device supports output voltages from 1.2 V to 3.3 V, depending on the specific model variant. It utilizes a 10-lead LFCSP package and includes precision enable functionality.
Feature Summary
- Ultralow noise architecture achieving excellent line and load transient response using only a 10 µF ceramic output capacitor.
- High power supply rejection ratio optimized for radio frequency applications to minimize interference.
- Precision enable pin with defined logic thresholds and internal discharge resistors for rapid shutdown.
- Integrated thermal protection and undervoltage lockout circuits to ensure operational reliability.
Applications
- Phase-locked loops (PLLs)
- Voltage controlled oscillators (VCOs)
- Backhaul and microwave links
Procurement Notes
Verify the exact suffix against the manufacturer's ordering guide to confirm the specific output voltage range and PSRR optimization level. Confirm package type and moisture sensitivity class prior to assembly. Ensure compatibility with the required PCB layout guidelines for thermal management and stability.
Selection Notes
Select this component when designing noise-sensitive RF circuits requiring high current capability. Evaluate the input-to-output voltage differential to manage power dissipation effectively. Consider the specific -02 model characteristics regarding PSRR at different frequencies compared to other variants in the series.
Part Context
This part belongs to the ADP7159 family of low-dropout regulators designed for demanding RF environments. It shares architectural similarities with related devices like the ADP7158 but offers adjustable output flexibility. The family targets infrastructure and communications systems where signal integrity is critical.
Replacement Considerations
Direct substitutes include other ADP7159 variants such as ADP7159ACPZ-01-R7 or ADP7159ACPZ-04-R7, provided the output voltage range and PSRR requirements match the design specifications. Verify pin compatibility and thermal performance before substitution.
