| The CP2308 is a high performance dual channel LDO for portable battery-powered systems. The excellent transient response performance, high PSRR characteristic and no bypass capacitor makes the CP2308 suitable for digital applications and occupies less PCB space. The CP2308 guarantees 200mA output current each channel and the typical dropout voltage is 150mV. Anti reverse current function can prevent reverse current in the situation that the output voltage is above the input voltage. The CP2308 has a fast turn-on time of 30¦ÌS and a fast turn-off time of 80¦ÌS typically. The quiescent current of the CP2308 is 60¦ÌA in working mode and the shutdown current of the CP2308 is less than 0.01¦ÌA. |
