DESCRIPTION:
The MSK 5175 series voltage regulators are available in +3.3V, +5.0V, +12.0V or adjustable output configura-
tions. 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 series also offers a TTL/CMOS compatible on/off enable function as well as an output flag pin. The MSK 5175
series is packaged in a space efficient 5 pin power SIP available in two styles with three lead bend options.

This parameter is guaranteed by design but need not be tested.
2
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.
3
Industrial grade devices shall be tested to subgroup 1 unless otherwise specified.
4
Military grade devices ('B' suffix) shall be 100% tested to subgroups 1,2 and 3.
