DESCRIPTION:
The MSK 5275 series voltage regulators are available in +1.5V, +1.7V, +1.9V, +2.5V, +3.3V, +5.0V and
+12.0V output configurations. All boast ultra low dropout specifications due to the utilization of a super PNP output
pass transistor with monolithic technology. Dropout voltages of 425mV at 7.5 amps are typical in this configuration,
which drives efficiency up and power dissipation down. Accuracy is guaranteed with a 1% maximum output voltage
tolerance. The MSK 5275 series is packaged in a space efficient 3 pin power surface mount ceramic package.

NOTES:
Output decoupled to ground using 33µF minimum capacitor 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 and 'E' suffix devices shall be tested to subgroup 1 unless otherwise specified.
Military grade devices ('H' suffix) shall be 100% tested to subgroups 1,2,3.
