ADM7151ACPZ-02-R7

Overview

The ADM7151ACPZ-02-R7 is an adjustable ultralow noise, high PSRR RF linear regulator from Analog Devices. It operates with an input voltage range of 4.5 V to 16 V and delivers a maximum output current of 800 mA. The output voltage is adjustable from 1.5 V to 5.1 V using external resistors. Key electrical parameters include a quiescent current of 4.3 mA at no load, a shutdown current of 0.1 µA, and an initial voltage accuracy of ±1%. The device features low dropout voltage characteristics and is stable with a 10 µF ceramic output capacitor.

Feature Summary

Ultralow noise performance with integrated filtering for sensitive RF applications
High power supply rejection ratio (PSRR) across a wide frequency range
Adjustable output voltage setting via external resistor divider
Low shutdown current consumption for power-efficient standby modes

Applications

RF mixers and phase-locked loops (PLLs)
Voltage-controlled oscillators (VCOs)
Clock distribution circuits
Ultrasound and imaging applications
High-speed analog-to-digital converters (ADCs)

Procurement Notes

Verify the specific suffix -R7 indicates reel packaging when sourcing. Confirm the -02 designation matches the required output voltage optimization for your input conditions. Ensure the LFCSP package thermal requirements are met in the final design. Check RoHS compliance status against current manufacturing revisions.

Selection Notes

Select this model when optimizing for lower power dissipation compared to the -04 variant. Verify that the input voltage headroom supports the desired output level while maintaining high PSRR. Consider the 8-lead LFCSP package size for compact board layouts. Evaluate thermal resistance based on the expected load current and ambient temperature conditions.

Part Context

This component belongs to the ADM7151 family of ultralow noise linear regulators designed specifically for radio frequency applications. The series offers high PSRR and minimal output noise to support precision signal processing. The -02 variant is tailored for specific input-output voltage combinations to enhance efficiency.
