Analog Devices Inc. ADP3303ARZ-5-REEL

Description
The ADP3303 is a high-accuracy, low-dropout linear regulator with an ultralow dropout voltage of 180 mV (typical) at 200 mA. It requires only a 0.47 uF output capacitor for stability and is insensitive to capacitor Equivalent Series Resistance (ESR). The ADP3303 operates with a wide input voltage range from 3.2 V to 12 V and delivers a load current in excess of 200 mA. It features an error flag that signals when the device is about to lose regulation or when the short circuit or thermal overload protection is activated. Other features include shutdown and optional noise reduction capabilities.
