AP7340 document number: ds35282 rev. 2 - 2 11 of 15 www.diodes.com october 2013 ? diodes incorporated a p7340 application information output capacitor an output capacitor (c out ) is needed to improve transient response and ma intain stability. the AP7340 is stable with very small ceramic output capacitors. the esr (equivalent series re sistance) and capacitance drives the selecti on. if the application has large load var iations, it is recommended to utilize low-esr bulk capacitors. it is recommended to place ceramic capacitors as close as possible to the load and the ground pin and care should be taken to reduce the impedance in the layout. input capacitor to prevent the input voltage from dropping during load st eps it is recommended to utilize an input capacitor (c in ). a minimum 0.47 f ceramic capacitor is recommended between v in and gnd pins to decouple input power supply glitch. th is 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 v in and gnd pins. enable control the AP7340 is turned on by setting the en pin high, and is turned o ff by pulling it low. if this feature is not used, the en pi n should be tied to v in pin to keep the regulator output on at all time. to ensure proper ope ration, the signal source used to drive the en pin must be abl e to swing above and below the specified turn-on/off voltage thresholds listed in the electrical characteristics section. short circuit protection when v out pin is short-circuit to gnd, short circuit protection will be triggered and clamp the output cu rrent to approxi mately 60ma. th is feature protects the regulator from over-cu rrent and damage due to overheating. layout considerations for good ground loop and stability, the input and output capacit ors should be located close to the input, output, and ground pi ns of the device. the regulator ground pin should be connected to the external circuit ground to reduce voltage drop caused by trace impedance. groun d plane is generally used to reduce trace impedanc e. wide trace should be used for large current paths from v in to v out , and load circuit. esr vs. output current ceramic type output capacitor is recommended for this series; howev er, the other output capacitors with low esr also can be use d. the relations between i out (output current) and esr of an output capacitor are shown below . the stable region is marked as the hatched area in the graph . measurement conditions: frequency band : 10hz to 2mhz, temperature : -40c to +85c
