MSK5021

HIGH CURRENT, SUPER LOW DROPOUT ADJUSTABLE VOLTAGE REGULATOR

M.S. Kennedy Corporation 

TYPICAL CONNECTION DIAGRAM

The above connection diagram illustrates an MSK 5021 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 applica-

tion note.

OUTPUT VOLTAGE ADJUSTMENT:

The output voltage of the MSK 5021 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 104 ((Vout/1.235)-1)
