Description

The 300 mA, adjustable dual outputADP223/ADP225and fixed dual outputADP222/ADP224combine high PSRR, low noise, low quiescent current, and low dropout voltage in a voltage regulator that is 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 ADP222/ADP223/ADP224/ADP225 extend the battery life of portable devices.The ADP222/ADP223/ADP224/ADP225 maintain power supply rejection greater than 60 dB for frequencies as high as 100 kHz while operating with a low headroom voltage. The ADP222/ADP223/ADP224/ADP225 offer much lower noise performance than competing LDOs without the need for a noise bypass capacitor. Overcurrent and thermal protection circuitry prevent damage in adverse conditions.The ADP224 and ADP225 are identical to the ADP222 and ADP223, respectively, but with the addition of a quick output discharge (QOD) feature.The ADP222/ADP223/ADP224/ADP225 are available in a small 8-lead, 2 mm x 2 mm LFCSP package and are stable with tiny 1 μF, ±30% ceramic output capacitors, resulting in the smallest possible board area for a wide variety of portable power needs.APPLICATIONSMobile phonesDigital camera and audio devicesPortable and battery-powered equipmentPortable medical devicesPost dc-to-dc regulation
