ADM7154ACPZ-3.3-R7

The ADM7154ACPZ-3.3-R7 is a high-performance linear regulator designed by AD(RoHS) for applications requiring ultralow noise and high Power Supply Rejection Ratio (PSRR). Operating from an input voltage range of 2.3 V to 5.5 V, it can deliver a maximum load current of 600 mA with a fixed 3.3 V output.

Key electrical characteristics include a typical dropout voltage of 120 mV at 600 mA load, a noise spectral density of 1.5 nV/√Hz from 10 kHz to 1 MHz, and integrated noise of 0.9 µV rms from 100 Hz to 100 kHz. The regulator also boasts a high PSRR of 90 dB from 200 Hz to 200 kHz, making it suitable for sensitive analog circuits.

Available in 8-lead LFCSP and SOIC packages, this regulator is designed for surface mount applications. Its precision enable feature and stable operation with a 10 µF ceramic output capacitor simplify design integration. The low quiescent current of 4 mA and very low shutdown current of 0.2 μA contribute to power efficiency.

Applications for the ADM7154ACPZ-3.3-R7 include regulation for noise-sensitive systems such as Phase-Locked Loops (PLLs), Voltage-Controlled Oscillators (VCOs), communications infrastructure, and backhaul systems.
