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 IN and GND. Output Capacitor The output capacitor is required to stabilize and help the transient response of the LDO. The AP7217D is designed to have excellent transient response for most applications with a small amount of output capacitance. The AP7217D is stable with any small ceramic output capacitors of 1.0μF 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 OUT and GND pins, and keep the leads as short as possible. The maximum power dissipation depends on the thermal resistance of IC package, PCB layout, the rate of surroundings airflow and temperature difference between junctions to ambient. The maximum power dissipation can be calculated by following formula: PD(MAX) = ( TJ(MAX) - TA ) / θJA Where TJ(MAX) is the maximum operation junction temperature 125°C, TA is the ambient temperature and the θJA is the junction to ambient thermal resistance. VIN IIN IOUT IN VOUT OUT AP7217D CIN COUT GND Iq ESR 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 approximately 850mA to prevent over-current and to protect the regulator from damage due to overheating. Short circuit protection When VOUT pin is shorted to GND or VOUT voltage is less than 200mV, short circuit protection will be triggered and clamp the output current to approximately 200mA. Thermal Considerations Thermal Shutdown Protection limits power dissipation in AP7217D. When the operation junction temperature exceeds 150°C, the Over Temperature Protection circuit starts the thermal shutdown function and turns the pass element off. The pass element turn on again after the junction temperature cools by 30°C. For continuous operation, do not exceed recommend maximum operation junction temperature 125°C. The power dissipation definition in device is: PD = (VIN − VOUT) x IOUT + VIN x IQ AP7217D Rev. 2 7 of 9 www.diodes.com FEBRUARY 2009 © Diodes Incorporated AP7217D 1.2V 600mA CMOS LDO Marking Information (1) SOT89-3L ( Top View ) XX : N4 : AP7217D-12 Y : Year : 0~9 W : Week : A~Z : 1~26 week; a~z : 27~52 week; z represents 52 and 53 week X : Internal code A~Z : Green XX Y W X 1 Package Information 2 3 (All Dimensions in mm) (1) Package Type: SOT89-3L 1.40/1.75 Typ 1.60 2.7 3.94/4.25 1.45/1.55 Typ 1.50 1.3 1.9 0.4 0.80/ 1.20 2.35/2.60 Typ 2.48 1.7 1.5 0.9 Land Pattern Recommendation (Unit: mm) 2.90/3.10 Typ 3.00 50 (2x) 80 (2x) 1.40/1.60 Typ 1.50 4.40/4.60 Typ 4.50 0.36/0.48 0.41/0.53 0.36/0.48 Typ 0.42 Typ 0.47 Typ 0.42 AP7217D Rev. 2 0.35/0.43 Typ 0.39 8 of 9 www.diodes.com FEBRUARY 2009 © Diodes Incorporated AP7217D 1.2V 600mA CMOS LDO IMPORTANT NOTICE Diodes Incorporated and its subsidiaries reserve the right to make modifications, enhancements, improvements, corrections or other changes without further notice to any product herein.
