DESCRIPTION:
The MSK5116 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 350mV at 1.5 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 MSK5116 series is packaged in a space efficient 5 pin power SIP available in two styles with
three lead bend options.
