1 Output decoupled to ground using 47μF minimum capacitor unless otherwise specified.
MSK5250-1.9
+1.9V
2 This parameter is guaranteed by design but need not be tested.
Typical parameters are representative of actual device performance but are for reference only.
MSK5250-2.5
+2.5V
3 All output parameters are tested using a low duty cycle pulse to maintain TJ = TC.
MSK5250-3.3
+3.3V
4 Industrial grade devices shall be tested to subgroup 1 unless otherwise specified.
5 Military grade devices ('H' suffix) shall be 100% tested to subgroups 1,2,3.
MSK5250-5.0
+5.0V
6 Subgroup 1 TC = +25°C
Subgroup 2 TJ = +125°C
MSK5250-12
+12.0V
Subgroup 3 TA = -55°C
7 Please consult the factory if alternate output voltages are required.
8 Due to current limit, maximum output current may not be available at all values of VIN-VOUT and temperatures.
See typical performance curves for clarification.
9 The output current limit function provides protection from transient overloads but it may exceed the maximum continuousrating.
Continuous operation in current limit may damage the device.
10 Continuous operation at or above absolute maximum ratings may adversely effect the device performance and/or life cycle.
