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 VIN and GND. Suggested Input Capacitance Vendor Capacitance TAIYO YUDEN 1μF 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 VIN 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 VEH and VEL. VROUT 0V 3.3V VDOUT Φ Φ Type Series Ceramic LMK212B EN=0 EN=1 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 1.0μF 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 VROUT and GND pins, and keep the leads as short as possible. Suggested Output Capacitance Vendor Capacitance Type Series TAIYO YUDEN 1μF Ceramic LMK212B Suggested Resistance Vendor Capacitance YAGEO SMD Current Limit Protection When output current at VROUT 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 VROUT voltage is less than 200mV, short circuit protection will be triggered and clamp the output current to approximately 50mA. VDOUT (reset output) ---Open-Drain Active-Low reset output--In general, VDOUT is pulled up by a resistor (100KΩ) to VIN. The AP7215 microprocessor (μP) supervisory circuitry asserts a guaranteed logic-low reset during power-up and power-down. Reset is asserted when VIN is below the reset threshold and remain asserted for at least tRP after VIN rises above the reset threshold. As long as VIN is lower than the reset threshold, VDOUT remains at logic "0". When VIN becomes higher than VHYS, a logic "1" is asserted after a 20ms time delay defined by tRP Type FR-SK AP7215 Rev. 1 8 of 11 www.diodes.com FEBRUARY 2009 © Diodes Incorporated AP7215 600mA CMOS LDO Marking Information (1) SOP-8L ( Top View ) 8 5 Logo Part Number AP7215-33 YY WW X X 1 4 YY : Year : 08, 09,10~ WW : Week : 01~52; 52 represents 52 and 53 week X : Internal Code G : Green (2) SOT89-3L ( Top View ) XX : Identification code 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 Identification Code N8 XX YWX 1 2 3 Device AP7215Y Package type SOT89-3L AP7215 Rev. 1 9 of 11 www.diodes.com FEBRUARY 2009 © Diodes Incorporated AP7215 600mA CMOS LDO Package Information (1) Package Type: SOP-8L (All Dimensions in mm) 3.85/3.95 5.90/6.10 0.10/0.20 0.254 0.62/0.82 Gauge Plane Seating Plane Detail "A" 7°~9° 1.30/1.50 1.75max. 0.15/0.25 0.35max. 45° 7°~9° Detail "A" 0°/8° 1.27typ 4.85/4.95 0.3/0.5 8x-0.60 5.4 6x-1.27 8x-1.55 Land Pattern Recommendation (Unit: mm) (2) Package Type: SOT89-3L 1.40/1.75 Typ 1.60 1.7 2.35/2.60 Typ 2.48 3.94/4.25 0.4 1.9 1.3 1.45/1.55 Typ 1.50 2.90/3.10 Typ 3.00 80 (2x) 4.40/4.60 Typ 4.50 1.40/1.60 Typ 1.50 0.80/ 1.20 1.5 0.9 Land Pattern Recommendation (Unit: mm) 50 (2x) 0.36/0.48 0.41/0.53 0.36/0.48 Typ 0.42 Typ 0.47 Typ 0.42 0.35/0.43 Typ 0.39 AP7215 Rev. 1 10 of 11 www.diodes.com 2.7 FEBRUARY 2009 © Diodes Incorporated AP7215 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.
