| Preliminary Datasheet 300mA FIXED OUTPUT VOLTAGE LDO REGULATOR General Description The AP2115 is positive voltage regulator IC designed by CMOS process. The AP2115 has features of low dropout voltage, high output voltage accuracy and low current consumption. It consists of a voltage reference, an error amplifier, a resistor network for setting output voltage, a current limit circuit for current protection, a circuit for over temperature protection and a chip enable circuit. Thus, the AP2115 is suitable for various power sources for portable application. The AP2115 is available in standard SOT-23-5 package.
