Available with Three Lead Form Options
DESCRIPTION:
The MSK 5012 voltage regulator output is fully programmable through the use of two external resistors. Ultra low
dropout voltage specifications are realized due to the unique output configuration which uses an extremely low
Rds(on)
MOSFET as a pass element. Dropout voltages of 0.45V at ten amps are typical in this configuration which drives
efficiency up and power dissipation down. Accuracy is guaranteed with a ±1% initial output voltage tolerance that
only varies ±2% with temperature. The MSK 5012 is packaged in a space efficient 5 pin SIP package that is
electrically isolated from the internal circuitry allowing direct heat sinking for efficient thermal dissipation.

This parameter is guaranteed by design but need not be tested. Typical parameters are representative of actual device
2
performance at 25°C but are for reference only.
All output parameters are tested using a low duty cycle pulse to maintain TJ = TC.
