The AP7347DQ is stable with very small ceramic output capacitors. The ESR (equivalent series resistance) and capacitance drives the selection. If the application has large load variations, it is recommended to utilize low-ESR bulk capacitors. It is also recommended to place ceramic capacitors as close as possible to the load and the ground pin. Care should be taken to reduce the impedance in the layout. Input Capacitor To prevent the input voltage from dropping during load steps, it is recommended to utilize an input capacitor (CIN). A minimum 1μF ceramic capacitor is recommended between the VIN and GND pins to decouple input power supply glitch. This input capacitor must be located as close as possible to the device to assure input stability and reduce noise. For PCB layout, a wide copper trace is required for both VIN and GND pins. Enable Control The AP7347DQ is turned on by setting the EN pin high, and is turned off by pulling it low. If this feature is not used, the EN pin should be tied to VIN pin to keep the regulator output on at all times. To ensure proper operation, the signal source used to drive the EN pin must be able to swing above and below the specified turn-on/off voltage thresholds listed in the Electrical Characteristics section. Short-Circuit Protection When the VOUT pin short-circuits to GND, short-circuit protection will be triggered and clamp the output current to approximately 55mA. This feature protects the regulator from overcurrent and damage due to overheating. Layout Considerations For good ground loop and stability, the input and output capacitors should be located close to the input, output, and ground pins of the device. The regulator ground pin should be connected to the external circuit ground to reduce voltage drop caused by trace impedance. Ground plane is generally used to reduce trace impedance. Wide trace should be used for large current paths from VIN to VOUT, and load circuit. ESR vs. Output Current A ceramic type output capacitor is recommended for this series; however, other output capacitors with low ESR can also be used. The relationship between the IOUT (output current) and the ESR of an output capacitor are shown below. The stable region for the safe operating temperature (-40°C ~ +85°C) is marked as the gray area in the graph. Measurement conditions: Frequency Band: 10Hz to 2MHz, Temperature: -40°C to +85°C.
