AP7215 Rev. 1 8 of 11 FEBRUARY 2009 www.diodes.com © Diodes Incorporated Application Note Input Capacitor A 1μF ceramic capacitor is recommended to connect between VIN and GND pins to decouple input power supply glitch and noise. The amount of the capacitance may be increased without limit. A lower ESR (Equivalent Series Resistance) capacitor allows the use of less capacitance, while higher ESR type requires more capacitance. This input capacitor must be located as close as possible to the device to assure input stability and less noise. For PCB layout, a wide copper trace is required for both V IN and GND. Suggested Input Capacitance Vendor Capacitance Type Series TAIYO YUDEN 1 μF Ceramic LMK212B Output Capacitor The output capacitor is required to stabilize and help the transient response of the LDO. The AP7215 is designed to have excellent transient response for most applications with a small amount of output capacitance. The AP7215 is stable with any small ceramic output capacitors of 1.0 μF or higher value, and the temperature coefficients of X7R or X5R type. Additional capacitance helps to reduce undershoot and overshoot during transient. For PCB layout, the output capacitor must be placed as close as possible to VR OUT and GND pins, and keep the leads as short as possible. Suggested Output Capacitance Vendor Capacitance Type Series TAIYO YUDEN 1 μF Ceramic LMK212B Suggested Resistance Vendor Capacitance Type YAGEO SMD FR-SK ENABLE/SHUTDOWN Operation The AP7215 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 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 under V EH and VEL. Current Limit Protection When output current at VR OUT pin is higher than current limit threshold, the current limit protection will be triggered and clamp the output current to approximately 750mA to prevent over-current and protect the regulator from damage due to overheating. Short circuit protection When VROUT pin is shorted to GND or VR OUT voltage is less than 200mV, short circuit protection will be triggered and clamp the output current to approximately 50mA. VD OUT (reset output) ---Open-Drain Active-Low reset output--- In general, VDOUT is pulled up by a resistor (100K Ω) to VIN. The AP7215 microprocessor ( μP) supervisory circuitry asserts a guaranteed logic-low reset during power-up and power-down. Reset is asserted when V IN is below the reset threshold and remain asserted for at least t RP after V IN rises above the reset threshold. As long as V IN is lower than the reset threshold, VDOUT remains at logic "0". When V IN becomes higher than V HYS, a logic "1" is asserted after a 20ms time delay defined by tRP VR OUT VD OUT EN=0 0V Φ EN=1 3.3V Φ
