1 Output decoupled to ground using 28μF minimum capacitance unless otherwise specified.

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.

3 All output parameters are tested using a low duty cycle pulse to maintain TJ = TC.

4 Industrial grade and "E" suffix devices shall be tested to subgroup 1 unless otherwise specified.

5 Military grade devices ('B' suffix) shall be 100% tested to subgroups 1,2 and 3.

6 Subgroup 1 TC=+25°C

Subgroup 2 TJ=+125°C

Subgroup 3 TA=-55°C

7 Please consult the factory if alternate output voltages are required.

8 Applies to MSK5175-00 adjustable version only.

9 Applies to fixed output devices only.

10 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.

11 The output current limit function provides protection from transient overloads but it may exceed the

maximum continuous rating. Continuous operation in current limit may damage the device.

12 Continuous operation at or above absolute maximum ratings may adversely effect the device perfor-

mance and/or life cycle.
