DESCRIPTION:
The MSK 5131 series voltage regulators are available in +1.5V,+1.7V,+1.8V,+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 350mV at 3 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 5131 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 27µF 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
8
temperatures. See typical performance curves for clarification.
Continuous operation at or above absolute maximum ratings may adversely effect the device
