Application Information

An output capacitor (COUT) is required to improve transient response and maintain stability. The AP7315Q 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 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 0.47μF ceramic capacitor is recommended between 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 AP7315Q 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 the V IN pin to keep the regulator output on at all time. 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 V OUT pin is short-circuit-to-GND, short-circuit protection is triggered and clamp the output current to approximately 60mA. This feature protects the regulator from over-current and damage due to overheating. Layout Considerations For good ground loop and stability, the input and output capacitors should be located close to the V IN, VOUT, and GND pins of the device. The regulator GND 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 may also be used. The relations between IOUT (Output Current) and ESR of an output capacitor are shown below. The stable region is marked as the hatched area in the graph. Measurement Conditions: Frequency Band: 10Hz to 2MHz, Temperature: -40°C to +125°C AP7315Q
