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.

The maximum allow- able power dissipation is a function of the maximum junction temperature, TJ(max), the junction-to-ambient thermal resistance, θJA, and the ambient temperature, 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 tempera- ture, and the regulator will go into thermal shutdown. Absolute Maximum Ratings (Note 1)

Application Information

Regarding good performance of regulator stability, external capacitors required by the AP2202 should be prudently selected. Input Capacitor If there is more than 10 inches of wire between the input and the AC filter, or if a battery is used as the input, a 1µF capacitor should be placed from IN to GND. Output Capacitor It is required to prevent oscillation. 1.0µF minimum is recommended when CBYP is unused. 2.2µF mini- mum is recommended when CBYP is 470pF. The out- put capacitor may be increased without limit for large values to improve transient response. In most cases, tantalum or aluminium electrolytic capacitors are adequate. Noise Bypass Capacitor Bypass capacitor is connected to the internal voltage reference. A 680pF capacitor connected from BYP to GND leads reference to be quiet which results in a significant reduction in output noise. When using CBYP, output capacitors of 2.2µF or greater are required for better stability. The start-up speed of the AP2202 is inversely proportional to the value of reference bypass capacitor. In some cases, if output noise is not a major concern and rapid turn-on is necessary, omit CBYP and leave BYP open. Figure 15. Typical Application of AP2202
