Description

The MSK5021 is a user adjustable voltage regulator capable of delivering 20 amps to a load with only a 0.5 volt dropout voltage rating. The output voltage is adjustable from 1.3 volts to 36 volts through the selection of two external resistors. Low dropout voltage ratings are achieved by employing a unique parallel MOSFET output pass transistor configuration which drives power dissipation down and efficiency up. Accuracy is guaranteed with a ±1% voltage tolerance at room temperature that only varies ±2% over temperature. A TTL level can be used to enable/ disable the device and a regulation dropou Fault pin provides a means of monitoring the output level. The MSK 5021 is packaged in a thermally efficient 12 pin power dip that can be bolted directly to a heat sink.
