The document describes the features and characteristics of the ADP1754/ADP1755 low VIN, low dropout linear regulators, including maximum output current, input voltage range, shutdown current, dropout voltage, accuracy, fixed output voltage options, adjustable output voltage option, PSRR, stability, load and line transient response, current-limit and thermal overload protection, power-good indicator, logic-controlled enable, and reverse current protection.
The ADP1754/ADP1755 regulators operate from 1.6 V to 3.6 V and deliver up to 1.2 A of output current. They are available in fixed‑output (ADP1754) and adjustable‑output (ADP1755) versions, both in a compact 16‑lead 4 mm × 4 mm LFCSP package. Key features include a very low shutdown current (<2 pA), low dropout voltage (105 mV @1.2 A), high power‑supply rejection ratio (up to 65 dB), and built‑in protection functions such as current‑limit, thermal shutdown, reverse‑current protection and a power‑good indicator.
Typical applications cover server computers, memory modules, telecommunications and network equipment, DSP/FPGA power supplies, and instrumentation. The datasheet provides detailed specifications, recommended capacitor values, absolute maximum ratings, thermal data, pin configurations, and an ordering guide for the various voltage options.
