DESCRIPTION:

The MSK 5151 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 370mV at 5 amps are typical in this configuration, which drives effi-

ciency 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 5151 series is packaged in a space efficient 5

pin power SIP available in two styles with three lead bend options.
