PSRR runs 56 dB at 1 kHz and rolls to 51 dB at 100 kHz — this profile suppresses switching-regulator ripple in the 10 kHz to 100 kHz range by roughly three orders of magnitude, making it a clean post-regulation stage for noise-sensitive analog supplies. ## Control and protection for sequencing Enable, Power Good, and Soft Start are on-chip — the Enable pin lets a supervisor sequence the rail on/off, Power Good flags the output when it reaches regulation, and Soft Start limits inrush current during startup. Over-current, over-temperature, and reverse-polarity protection cover the common fault modes without external clamp diodes. Quiescent current is 800 µA typical; the maximum supply current is 1.8 mA — the overhead is low enough for always-on rails in battery-powered gear where the LDO stays enabled.","metaTitle":"ADP1740ACPZ-2.5-R7 LDO Regulator, 2A, 2.5V Fixed, 16-LFCSP","metaDescription":"Analog Devices ADP1740ACPZ-2.5-R7 LDO, 2A fixed 2.5V output, 0.28V dropout at 2A, PSRR 56dB-51dB (1-100kHz), -40°C to 125°C, 16-LFCSP.
