DESCRIPTION:

The MSK 5101 series voltage regulators are available in +3.3V, +5.0V, +12.0V or adjustable output 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% output voltage tolerance. The series also offers a TTL/CMOS

compatible on/off enable function as well as an output flag pin on the fixed voltage versions. The MSK 5101 series is

packaged in a space efficient 10 pin ceramic flatpack with a built in metal base.
