ADI ADP3303ARZ-3.3

正12V200mA

Overview

GENERAL DESCRIPTION  The ADP3303ARZ-3.3 is a member of the ADP3300, ADP3301, and ADP3309 family of precision low dropout anyCAP1 voltage regulators. The ADP3303ARZ-3.3 stands out from the conventional LDOs with a different architecture, an enhanced process, and a different package. Its patented design requires only a 0.47 μF output capacitor for stability. This device is insensitive to capacitor Equivalent Series Resistance (ESR) and is stable with any good quality capacitor, including ceramic types (MLCC) for space restricted applications. The ADP3303ARZ-3.3 achieves exceptional accuracy of ±0.8% at room temperature and ±1.4% overall accuracy over temperature, line, and load regulations. The dropout voltage of the ADP3303ARZ-3.3 is only 180 mV (typical) at 200 mA.  In addition to the architecture and process, the Analog Devices, Inc., proprietary thermally enhanced package (Thermal Coastline) can handle 1 W of power dissipation without external heatsink or large copper surface on the printed circuit board (PCB).  This keeps PCB real estate to a minimum and makes the ADP3303ARZ-3.3 very attractive for use in portable equipment.  The ADP3303ARZ-3.3 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. The ADP3300, ADP3301, and ADP3309 anyCAP LDO family offers a wide range of output voltages and output current levels:
