MSK5021 Datasheet, PDF (5/6 Pages) M.S. Kennedy Corporation – HIGH CURRENT, SUPER LOW DROPOUT ADJUSTABLE VOLTAGE REGULATOR

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)
