This input capacitor should 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 AP7201 requires a minimum of 0.22μF capacitance on each output to stabilize the transient response of the LDO. The AP7201 is designed to have excellent transient response for most applications with a small amount of output capacitance. A ceramic capacitor is recommended on each channel to connect between OUT and GND pins. The device is also stable with multiple capacitors in parallel, which can be of any type of value. Larger capacitance helps to reduce undershoot and overshoot during transient and provides better stability and noise performance. This output capacitor should be placed as close as possible to OUT and GND pins for optimum performance. 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. AP7201 Rev. 3 ENABLE/SHUTDOWN Operation The AP7201 is turned on by setting the EN pin high by pulling to input voltage (VIN), and is turned off by pulling it low (GND). The EN function allows the output of each regulator to be turned off independently, resulting in greatly reduced power consumption. 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 VIL and VIH. Current Limit Protection In the presence of a short or excessive condition, the AP7201 uses an internal fold-back mechanism that triggers the protection and clamps the output approximately 300mA. load current short circuit current limit current to Short Circuit Protection When OUT pin is short-circuited to GND or OUT voltage is less than 200mV, short circuit protection be triggered and clamp the output current approximately 40mA typical. This feature protects regulator from over-current and damage due overheating. 10 of 13 www.diodes.com pin will to the to MAY 2014 © Diodes Incorporated DISCONTINUED AP7201 DUAL 150mA LOW DROPOUT LINEAR REGULATOR Application Note (Continued) Wide Fixed Output Range The AP7201, with a wide fixed output range of 1V to 3.3V, provides a versatile solution for many portable and low power applications. Low Quiescent Current The AP7201, consuming only around 25µA for all input range, provides great power saving in portable and low power applications. Thermal Shutdown Protection Thermal protection disables both outputs when the junction temperature rises to approximately +145°C, allowing the device to cool down. When the junction temperature reduces to approximately +130°C 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. PD = ( VIN − VOUT )xIOUT The AP7201 is available in the DFN2818-6 package with exposed pad, which is the primary conduction path for heat to the printed circuit board (PCB). The pad can be connected to ground or be left floating; however, to ensure the device will not overheat, it should be attached to an appropriate amount of copper PCB area. 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: PD (max@ TA ) = ( +145°C − TA ) R θJA 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: AP7201 Rev. 3 11 of 13 www.diodes.com MAY 2014 © Diodes Incorporated DISCONTINUED AP7201 DUAL 150mA LOW DROPOUT LINEAR REGULATOR Marking Information (1) DFN2018-6 (USP-6B) ( Top View ) AA BB .Y WW X AA : Output 1 BB : Output 2 Y : Year "7" : 2007 "8" : 2008 WW : Month 01~52 X : G : Green Marking ID Code Table Device AP7201-1818FM AP7201-1828FM AP7201-2828FM Package Information ID Code 1818 1828 2828 ( All Dimensions in mm ) 2X0.25 A 0.08 C 0.545/0.605 6X- 0/0.05 0.10 C 0.13Typ (1) DFN2018-6 (USP-6B) Seating Plane Side View C 1.75/1.875 B A Pin #1 ID 1.3/1.5 0.9/1.1 1.95/2.075 0.2/0.3 CL CL 0.30Typ 2X- 0.25 B 0.50Typ 0.15/0.25 0.10 C A B Bottom View AP7201 Rev. 3 12 of 13 www.diodes.com MAY 2014 © Diodes Incorporated DISCONTINUED AP7201 DUAL 150mA LOW DROPOUT LINEAR REGULATOR Taping Orientation Notes: (Note 7) 7.
