typical applications 5501 series m.s.kennedy corp. features: reliable-critical automotive aeronautics & aerospace down-hole precision regulators / references a/d and d/a converters current sources. high temperature low dropout regulator equivalent schematic typical applications the msk5501 is an ultra low dropout, high temperature linear voltage regulator capable of delivering 100ma of output current at 200c. typical dropout voltage is 71mv with a 100ma load. this is a voltage controlled device and drive current does not increase with output current. the devise?s supply current is typically constant from no load to maximum load. this device also has internal current limit protection. when the current limiting engages, the output voltage will decrease linearly until the over current condition ends. the msk5501 is specifically designed for automotive, aeronautics and aerospace, and down-hole applications. the device is packaged in a hermetically sealed 5 pin sip that is electrically isolated from internal circuitry for direct heat sinking. pin-out information enable vin vout gnd gnd 1 2 3 4 5 1 description: preliminary rev. - 9/14 mil-prf-38534 and 38535 certified facility operational from -55c to +200c input voltage range from +5v to +10v available in 1.8v output voltage alternate output voltages available ultra low dropout for reduced power consumption output current up to 100ma @ 200c over current limiting standby quiescent current is typically 1 a external enable (active low) available in four lead options: straight, up, down, and gull wing contact msk for qualification status

application notes vin - this pin provides the input power connection to the msk5501. gnd - these pins provide the input and output ground refer- ence. vout - this pin is the output for the device. enable - when tied low, the msk5501 is enabled and oper- ates normally. when tied high, the msk5501 is disabled. input and output power supply bypassing 3 the msk5501 has an internal output capacitor, which in most cases, is sufficient to stabilize the internal control loop. additional capacitance can be added, and improves load tran- sient response. although not required, a 0.047 f ceramic capacitor connected between vin and gnd, can be used to maximize transient response and minimize power supply tran- sients. thermal limiting tbd over current protection the msk5501 has an internal current limiting feature. the typical current limit threshold is 350ma. during an over current event, the output voltage with be reduced linearly until the over current state ends. enable function when the enable pin is tied low (< 0.9v), the msk5501 is enabled and operates normally. when the enable pin is tied high (>1.7v), the msk5501 is disabled and vout is floating. should the output voltage rise above vin, or vin drop below the output voltage, an internal back diode will conduct reverse current. supply current, when disabled, is typically 1 a. preliminary rev. - 9/14 pin function
