application notes vin - these pins provide the input power connection to the msk 5500-15. gnd - these pins provide the input and output ground reference. vout - these are the output pins for the device. all three pins must be connected for proper operation. shdn - this pin is used to disable the output and is logic low. input and output bypassing 3 pin functions proper input bypassing is required in order to filter out noise and provide low ac impedance source. the msk 5500-15 has an internal 0.1uf ceramic capacitor connected between vin and gnd. in most application the internal input capacitor will be sufficient for proper operation. additional input capacitance can be added to maximize transient response and minimize power supply tran- sients. for stability the msk 5500-15 has an internal 0.2uf low esr capacitor connected between vout and gnd. to improve transient response additional capacitance up to 4.7uf can be added if needed. thermal limiting the msk 5500-15 has no internal thermal shutdown feature. operation above 232c is possible at the expensive of reducing product lifetime. overcurrent protection the msk 5500-15 has a short circuit protection feature it is, however, not able to sink current. doing so could damage the regulator. start up options the msk 5500-15 has been designed to provide a soft-start with little to no overshoot. if slight overshoot is observed when turning on into a light load adding output capacitance will elimi- nate the overshoot. shutdown the msk 5500-15 has a shut-down feature that will set the output of the regulator to high impedance. the feature helps re- duce power consumption by 90% in power-critical applications. a voltage lower then 0.6v on the shdn pin will put the regula- tor into shut-down mode. a voltage of greater than 2.3v on the shdn pin will turn the regulator on. 8548-107 rev. a 8/13
