The amount of the capacitance may be increased without limit. 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 IN and GND pins. A lower ESR capacitor type allows the use of less capacitance, while higher ESR type requires more capacitance. Output Capacitor The output capacitor is required to stabilize and improve the transient response of the LDO. The AP7366 is stable with very small ceramic output capacitors. Using a ceramic capacitor value that is at least 2.2F with 10m ESR 300m on the output ensures stability. Higher capacitance values help to improve line and load transient response. The output capacitance may be increased to keep low undershoot and overshoot. Output capacitor must be placed as close as possible to OUT and GND pins. AP7366 Document number: DS41529 Rev. 3 - 2 8 of 15 www.diodes.com September 2019 (c) Diodes Incorporated AP7366 Application Information (continued) NEW PRODUCT Adjustable Operation The AP7366 provides output voltage from 0.8V to 5.0V through external resistor divider as shown below. The output voltage is calculated by: Where VREF = 0.8V (the internal reference voltage) Rearranging the equation will give the following that is used for adjusting the output to a particular voltage: To maintain the stability of the internal reference voltage, R2 needs to be kept smaller than 80k. No Load Stability Other than external resistor divider, no minimum load is required to keep the device stable. The device will remain stable and regulated in no load condition. ON/OFF Input Operation The AP7366 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 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 under VIL and VIH. Current Limit Protection When output current at OUT pin is higher than current limit threshold, the current limit protection will be triggered and clamp the output current to prevent over-current and to protect the regulator from damage due to overheating. Short Circuit Protection When OUT pin is short-circuit to GND, short circuit protection will be triggered and clamp the output current to approximately 250mA. Full current is restored when the output voltage exceeds 15% of VOUT. This feature protects the regulator from over-current and damage due to overheating. Thermal Shutdown Protection Thermal protection disables the output when the junction temperature rises to approximately +150C, allowing the device to cool down. When the junction temperature reduces to approximately +130C, the output circuitry is enabled again. Depending on power dissipation, thermal resistance, and ambient temperature, the thermal protection circuit may cycle on and off. This cycling limits the heat dissipation of the regulator, protecting it from damage due to overheating. AP7366 Document number: DS41529 Rev. 3 - 2 9 of 15 www.diodes.com September 2019 (c) Diodes Incorporated AP7366 Application Information (continued) Ultra Fast Start-Up After enabled, the AP7366 is able to provide full power in as little as tens of microseconds, typically 200s, without sacrificing low ground current. This feature will help load circuitry move in and out of standby mode in real time, eventually extend battery life for mobile phones and other portable devices. Low Quiescent Current NEW PRODUCT The AP7366, consuming only around 60A for all input range, provides great power saving in portable and low power applications. Power Dissipation The device power dissipation and proper sizing of the thermal plane that is connected to the thermal pad is critical to avoid thermal shutdown and ensure reliable operation. Power dissipation of the device depends on input voltage and load conditions and can be calculated by: The maximum power dissipation, handled by the device, depends on the maximum junction to ambient thermal resistance, maximum ambient temperature, and maximum device junction temperature, which can be calculated by the equation in the following.
