This helps reduce any parasitic resistance in series with the load. Stability and Decoupling Capacitors Input Capacitors To ensure stable operation, the input supply must be low impedance up to a frequency of a few MHz. This requires a closely placed input decoupling capacitor of 4.7F minimum. This can be either ceramic or solid tantalum. The ESR of this capacitor must be less than 0.5. Output Capacitor The AP1117 also requires a closely placed output capacitor as part of the device frequency compensation. As part of its improved performance over industry standard 1117, the AP1117 is suitable for use with MLCC (Multi-Layer Ceramic Chip) capacitors. A minimum output capacitor of 4.7F ceramic X7R or 4.7F solid tantalum is required. Aluminum electrolytic can be used but a minimum of 47F is required. When using Aluminum electrolytic it is still recommended to also use a 1F MLCC in parallel. The ESR of the output capacitors must be less than 0.5. The AP1117 is stable when using the correct value of MLCC capacitors. When using MLCC capacitors X7R dielectric is recommended. Do not use Y5V dielectrics. Capacitor Track Length Both input and output capacitors must be placed close to the AP1117. PCB traces not longer than 10mm are recommended between the AP1117 and the capacitors. Thermal Considerations Thermal protection circuitry will shut down the regulator should the junction temperature exceed typically +150C at the sense point. The AP1117 is pin compatible with similar `1117 regulators and offers extended temperature range and improved regulation specifications. AP1117 series regulators have internal thermal limiting circuitry designed to protect the device during overload conditions. For continuous normal load conditions however, the maximum junction temperature rating of +125C must not be exceeded. It is important to give careful consideration to all sources of thermal resistance from junction to ambient. For the SOT223 and TO252 packages, which are designed to be surface mounted, additional heat sources mounted near the device must also be considered. Heat sinking is accomplished using the heat spreading capability of the PCB and its copper traces. The JC (junction to tab) of the TO252 and SOT223 are +12C/W and +15C/W respectively. Thermal resistances from tab to ambient can be as low as 30C/W. The total thermal resistance from junction to ambient (JA) can be as low as +42 ~ +46C/W. This requires a reasonable sized PCB with at least one layer of copper to spread the heat across the board and couple it into the surrounding air. Datasheet specifications using 2 oz copper and a 5mm x 5mm pad with TA = +27C, no air flow yielded JA (junction to tab) of +73C/W and +107C/W for TO252 and SOT223 respectively. The thermal resistance for each application will be affected by thermal interactions with other components on the board. Some experimentation will be necessary to determine the actual value. See graphs of power dissipation and thermal pictures of different size PCB copper area for guidance.
