The 200 mA dual output ADP220 / ADP221 combine high PSRR, low noise, low quiescent current, and low dropout voltage in a voltage regulator ideally suited for wireless applications with demanding performance and board space requirements.
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 overcurrent and thermal protection to prevent damage in adverse conditions.
