That PSRR curve is the part's main event: it keeps switching-regulator ripple and high-frequency noise off sensitive analog, RF, or data-converter supply rails. The dropout voltage maxes at 0.21 V at full load, so a 3.3 V rail can regulate down to 2.9 V with only 3.6 V input — useful in systems where the input bus sags under transient load. ## Package, temperature, and protection — design-in checklist Housed in an 8-WFDFN exposed-pad CSP (8-LFCSP-WD, 3x3 mm), surface-mount only. Protection features include over-current and over-temperature shutdown; an enable pin lets the system sequence the rail on and off. Quiescent current is 7 mA typical, supply current maxes at 10 mA.","metaTitle":"ADM7155ACPZ-03-R7 LDO Regulator, 600mA, Adjustable, 8-LFCSP","metaDescription":"Analog Devices ADM7155ACPZ-03-R7 LDO: 600mA adjustable output, 94dB PSRR at 1kHz, 210mV dropout max.
