AP2120
General Description
Features
The AP2120 series are positive voltage regulator ICs
fabricated by CMOS process. Each of these ICs con-
sists of a voltage reference, an error amplifier, a resis-
tor network for setting output voltage, a current limit
circuit for current protection.

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 2: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifica-
tions do not apply when operating the device outside of its operating ratings. The maximum allowable power dissipation is a
function of the maximum junction temperature, TJ(max), the junction-to-ambient thermal resistance, θJA, and the ambient tem-
perature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using: PD(max)=(TJ(max)
-
TA)/θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature.

Note: Filter capacitors are required at the AP2120's input and output. 1µF capacitor is required at the input. The
minimum output capacitance required for stability should be more than 1µF with ESR from 0.01Ω to 100Ω.
Ceramic capacitors are recommended.
