ADP3303

High Accuracy anyCAP® 200 mA Low Dropout Linear Regulator
Manufactured by:

Product Details

The ADP3303 is a member of the ADP330x family of precision low dropout anyCAP® voltage regulators. The ADP3303 stands out from the conventional LDOs with a novel architecture, an enhanced process and a new package. Its patented design requires only a 0.47 µF output capacitor for stability. This device is stable with any capacitor regardless of its ESR (Equivalent Series Resistance) value, including ceramic types (MLCC) for space restricted applications. The ADP3303 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 ADP3303 is only 180 mV (typical) at 200 mA.

In addition to the new architecture and process, ADI's new proprietary thermally enhanced package (Thermal Coastline) can handle 1 W of power dissipation without external heatsink or large copper surface on the PC board. This keeps PC board real estate to a minimum and makes the ADP3303 very attractive for use in portable equipment.

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. The ADP330x anyCAP® LDO family offers a wide range of output voltages and output current levels from 50 mA to 200 mA:

ADP3300 (50 mA, SOT-23)
ADP3301 (100 mA)
ADP3302 (100 mA, Dual Output)

Product Details

In order to get the correct unpopulated evaluation board with an appropriate Bill of Materials and Schematic, you need to use the button for "Request Evaluation Board" from within the design tool. Make sure the design tool is in a state that matches your desired power requirements.

This will create a template email that will request from us the proper blank evaluation board for that ADI part and your application's power parameters.


Note: Some parts have multiple blank boards for high/low current or for different topologies (Boost, SEPIC, SEPIC-Cuk), while other blank boards support multiple ADI parts. This is why it is important to run the design tool with your parameters before making your email request from the tool.
