Dual, 200 mA, Low Noise, High PSRR Voltage Regulator
The low quiescent current, low dropout voltage, and wide input voltage range of the ADP220/ADP221 extend the battery life of portable devices. The ADP220/ADP221 maintain power supply rejection greater than 60 dB for frequencies as high as 100 kHz while operating with a low headroom voltage. The ADP220 offers much lower noise performance than competing LDOs without the need for a noise bypass capacitor. The ADP221 also includes an active pull-down to quickly discharge output loads.
The ADP220/ADP221 are available in a miniature 6-ball WLCSP package and is stable with tiny 1 μF ± 30% ceramic output capacitors, resulting in the smallest possible board area for a wide variety of portable power needs.
The ADP220/ADP221 are available in many output voltage combinations, ranging from 0.8 V to 3.3 V, and offer overcur-rent and thermal protection to prevent damage in adverse conditions.

Simple device measurements such as line and load regulation, dropout, and ground current can be demonstrated with just a single voltage supply, a voltmeter, a current meter, and load resistors.
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.
