ADP1712/ADP1713/ADP1714 are low dropout CMOS linear regulators with an output current of 300 mA, an input voltage range of 2.5 V to 5.5 V, and a soft-start function. The output noise is low, the PSRR is high, and the output voltage has 16 fixed voltage options, which support reference voltage bypass and tracking functions.
The ADP1712, ADP1713, and ADP1714 are 300 mA low‑dropout linear regulators designed for mobile phones, digital cameras, audio devices, and other battery‑powered equipment. They operate from a 2.5 V to 5.5 V input range and offer 16 fixed output options or an adjustable output (0.8 V‑5 V) with soft‑start capability. Features include low ground‑current (75 µA at 100 µA load), shutdown current <1 µA, current‑limit and thermal‑overload protection, and an enable pin.
Key specifications are provided in the datasheet, including dropout voltage, line and load regulation, output noise, and power‑supply rejection ratio. The document also contains pin‑function tables, typical application circuits, thermal‑resistance data, PCB layout recommendations, and an ordering guide for the 5‑lead TSOT package.
