HIGH CURRENT, SUPER LOW DROPOUT ADJUSTABLE VOLTAGE REGULATOR

M.S. Kennedy Corporation 

TYPICAL CONNECTION DIAGRAM

The above connection diagram illustrates an MSK5021 regulator. Q1 turns on the Fault L.E.D. when pin 6 of the hybrid

drops to a logic low. Current into pin 6 is limited to approximately 1mA by the 12KΩ resistor from pin 5 to pin 6. The optimum

value of capacitance COUT may vary from one application to the next depending on the load applied. 10µF is a good starting

point. The ENABLE input is TTL compatible but can be tied to the input voltage when shutdown is not needed. RSC should

be selected for the desired current limit. See current limit connections application note.

OUTPUT VOLTAGE ADJUSTMENT:

The output voltage of the MSK5021 can be adjusted from +1.3 volts to +36 volts. Refer to the following formula for resistor

divider selection. R2 shall be 10KΩ for all applications.

RADJUST = 1 x 10 ((Vo4ut/1.235)-1)
