DESCRIPTION:  
The MSK 5046RH series are high efficiency, 5 amp, radiation hardened switching regulators. The output voltage is  
configured for 1.5V,1.7V,1.8V,1.9V,2.0V,2.5V,3.0V,3.3V,3.4V or 5.0V internally with a tolerance of 1%. The very  
low output impedance allows the MSK 5046RH to drive the start up surge current required by many CPU's and  
FPGA's with little or no decrease in the output voltage. The operating frequency of the MSK 5046RH is 350KHz. A  
low quiescent current and very good operating efficiency keep the total internal power dissipation of the MSK  
5046RH down to an absolute minimum. The device is packaged in a hermetic surface mountable package for high  
reliability applications.
