PSRR is specified at 60 dB across the 10 kHz to 100 kHz band — this is the frequency range where typical buck converter switching noise lives. A 60 dB rejection means the ripple at the output is 1,000× lower than the input ripple at those frequencies, which matters for ADC reference rails, VCO supplies, or any analog front-end where switching noise couples into the signal chain. ## Quiescent current and thermal envelope Quiescent current is 105 µA typical, with a maximum supply current of 280 µA. For always-on rails in battery-powered or energy-harvesting designs, this Iq sits below the self-discharge rate of a small lithium cell — the regulator's own draw does not dominate the standby budget. Without the pad soldered to a copper plane, the junction-to-ambient thermal resistance rises and the output current must be derated above 85°C ambient. Protection features include over-current, over-temperature, and under-voltage lockout (UVLO) — the UVLO threshold prevents the pass FET from operating in the linear region during input brownout, which would otherwise dissipate excessive power in the die. The 8-LFCSP footprint is shared with other members of the ADP125 family, so a pin-compatible drop-in exists if the output voltage or package variant needs to change.","metaTitle":"ADP125ACPZ-R7 LDO, 500mA, Adjustable, 8-LFCSP, PSRR 60dB","metaDescription":"Analog Devices ADP125ACPZ-R7 adjustable LDO, 500mA output, 0.23V dropout, PSRR 60dB (10kHz-100kHz).
