The ADP3205AJCPZ 200 mA triple output LDO combines high PSRR, lownoise, low quiescent current, and low dropout voltage in a voltageregulator ideally suited for wireless applications with demandingperformance and board space requirements.
The low quiescent current, low dropout voltage, and wide inputvoltage range of the ADP3205AJCPZ triple LDO extend the battery life ofportable devices. The ADP3205AJCPZ triple LDO maintains power supplyrejection greater than 60 dB for frequencies as high as 100 kHzwhile operating with a low headroom voltage. The ADP3205AJCPZ tripleLDO offers much lower noise performance than competing LDOswithout the need for a noise bypass capacitor.
The ADP3205AJCPZ triple LDO is available in a miniature 16-lead 3 mm ×3 mm LFCSP package and is stable with tiny 1 µF ±30% ceramic outputcapacitors, resulting in the smallest possible board area for a widevariety of portable power needs.
The ADP3205AJCPZ triple LDO is available in output voltage combinationsranging from 0.8 V to 3.3 V and offers over current andthermal protection to prevent damage in adverse conditions.
