DESCRIPTION:
The MSK 5020 series voltage regulators are available in a +3.3V, +5.0V or +12.0V fixed output configuration.
All three boast ultra low dropout specifications due to the utilization of a MOSFET output pass transistor with
extremely low Rds(on). Dropout voltages of 0.50V at 20 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
varies only ±2% with temperature. A TTL level can be used to enable/disable the device and a regulation dropout
fault pin provides a means of monitoring the output level. The MSK 5020 series is packaged in a thermally efficient
12 pin power dip.

NOTES:
Output decoupled to ground using 33µF minimum capacitor and RSC=0Ω unless otherwise specified.
This parameter is guaranteed by design but need not be tested. Typical parameters are representative of
actual device performance but are for reference only.
All output parameters are tested using a low duty cycle pulse to maintain TJ = TC.
Industrial grade devices shall be tested to subgroup 1 only unless otherwise specified.
Military grade devices ('B' suffix) shall be 100% tested to subgroups 1,2 and 3.

Please consult the factory if alternate output voltages are required.
