AP2115
General Description
Features
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.

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated
under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods
may affect device reliability.

Note 4: Dropout voltage is defined as the input-to-output differential when the output voltage drops to 98% of its nominal
value which is measured at VOUT+1V applied to VIN. The 1.8V version dropout voltage is limited by the input voltage range.
Note 5: Turn-on time is time measured between the enable input just exceeding VIH and the output voltage just reaching 95%
of its nominal value.
