DESCRIPTION:
The MSK 5176 series voltage regulators are available in +1.5V,+1.7V,+1.9V,+2.5V,+3.3V,+5.0V and +12.0V
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 series also offers a TTL/CMOS compatible on/off enable function. The MSK 5176 series is packaged in a space
efficient 5 pin power SIP available in two styles with three lead bend options.

NOTES:
Output decoupled to ground using 33µF minimum capacitance unless otherwise specified.
1
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 and "E" suffix devices shall be tested to subgroup 1 unless otherwise specified.
4
Military grade devices ('H' suffix) shall be 100% tested to subgroups 1,2 and 3.

Please consult the factory if alternate output voltages are required.
7
Due to current limit, maximum output current may not be available at all values of VIN-VOUT and temperatures. See typical
8
performance curves for clarification.
Continuous operation at or above absolute maximum ratings may adversely effect the device performance and/or life cycle.
