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.
