The ADP3303 is a high accuracy anyCAP™ 200 mA low dropout linear regulator with ultralow dropout voltage, high accuracy, low shutdown current, current and thermal limiting.
The ADP3303 is a precision low‑dropout (LDO) regulator from Analog Devices featuring 0.8 % line and load accuracy at 25 °C and 1.4 % overall accuracy across temperature, line and load. It operates from a 3.2 V to 12 V input range, provides up to 200 mA output current, and requires only a 0.47 µF anyCAP capacitor for stability, making it suitable for space‑constrained portable equipment.
Typical applications include cellular phones, notebook computers, battery‑powered systems, portable instruments, bar‑code scanners, and post‑regulation for switching supplies. The device is offered in a thermally enhanced SO‑8 package that dissipates up to 1 W without a heatsink, and includes features such as current limit, thermal shutdown, error flag, and noise‑reduction pin.
